Hint

Design a parking system for a parking lot. The parking lot has three kinds of parking spaces: big, medium, and small, with a fixed number of slots for each size.

Implement the ParkingSystem class:

• ParkingSystem(int big, int medium, int small) Initializes object of the ParkingSystem class. The number of slots for each parking space are given as part of the constructor.
• bool addCar(int carType) Checks whether there is a parking space of carType for the car that wants to get into the parking lot. carType can be of three kinds: big, medium, or small, which are represented by 1, 2, and 3 respectively. A car can only park in a parking space of its carType. If there is no space available, return false, else park the car in that size space and return true.

 

Example 1:

Input
["ParkingSystem", "addCar", "addCar", "addCar", "addCar"]
[[1, 1, 0], [1], [2], [3], [1]]
Output
[null, true, true, false, false]

Explanation
ParkingSystem parkingSystem = new ParkingSystem(1, 1, 0);
parkingSystem.addCar(1); // return true because there is 1 available slot for a big car
parkingSystem.addCar(2); // return true because there is 1 available slot for a medium car
parkingSystem.addCar(3); // return false because there is no available slot for a small car
parkingSystem.addCar(1); // return false because there is no available slot for a big car. It is already occupied.

 

Constraints:

• 0 <= big, medium, small <= 1000
• carType is 1, 2, or 3
• At most 1000 calls will be made to addCar

the problem:

runtime 3ms
memory 38.77 mb

Let's say I paid 96k, then went on with round 2 and now I'm uninterested in ipu counseling cuz I got a better college else where, then will I get 96k refund after round 2 or round 3?

USICT,mait,msit,usar etc please pics se reality show kri online to sb acche milre hai 😂

basically my college starts in 2 months and im studying cpp before it to start early, i use gemini pro to study. it made a 5 level plan, can someone knowledgeable please review it?

Phase 1: Fundamentals(conditional statements,loops basic syntax,indentaton)
.
Phase 2: Complex Data (2D Arrays & Strings)
.
Phase 3: Modularity (Functions & Scope)
.
Phase 4: Superpowers (References & Vectors)
.
Phase 5: Object-Oriented Programming (Structs & Classes)
.
Phase 6: Final Capstone Project

the basic format is

1. teaches me about the topic a little
2. 2)teaches me the syntax with an example
3. gives me 3 exercises one by one (i have to send it the code after each question)
4. gives me a final problem to evaluate my understanding of the concept (it involves everything of the past and then it rates it from S to F)
5. \*\* if it isnt S then it asks me to fix the errors. one of its lessons

The Concept: Classes and Objects

Up until now, you have been writing procedural code. If you wanted to track a student's data, you had to create separate, loose variables: a `string` for their name, an `int` for their age, and a `vector` for their test scores. If you had 50 students, managing those loose variables would become a nightmare.

Object-Oriented Programming changes the architecture. You create a **Class**, which acts as a blueprint. This blueprint bundles the data (variables) and the actions (functions) together into a single, cohesive unit.

When you use that blueprint to spawn an actual entity in your program, that entity is called an **Object**.

The Syntax Outline

C++

#include <iostream>
#include <string>
using namespace std;

// 1. Defining the Blueprint (Class)
class Server {
public: // This access modifier allows main() to interact with these variables
    
    // Attributes (Variables)
    string status;
    int ping;

    // Methods (Functions built inside the class)
    void printStatus() {
        // The method already knows its own variables. No need to pass parameters!
        cout << "Server Status: " << status << " | Ping: " << ping << "ms\\n";
    }
};

int main() {
    // 2. Instantiating an Object (Using the blueprint)
    Server proxy1; 
    
    // 3. Accessing the object's attributes and methods using the dot (.) operator
    proxy1.status = "Online";
    proxy1.ping = 24;
    
    proxy1.printStatus(); 

    return 0;
}

Exercise 1: The Score Tracker Class

**Target Mechanics:** Defining a class, setting attributes, and creating an internal method.

**The Objective:** We are going to build a system to track academic progress. You will write a `Student` class that manages its own mock exam scores and calculates its own average.

**The Requirements:**

1. **The Class Definition:** * Above `main()`, define a `class` named `Student`. * Include the `public:` access modifier. * Give it two attributes: a `string` named `name` and a `std::vector<int>` named `mockScores`.
2. **The Internal Method:** * Inside the class, write a function that returns an `int` (or `float`/`double` if you prefer precision) called `calculateAverage`. * This function should not take any parameters. It should simply iterate through the object's own `mockScores` vector, calculate the average, and return that value.
3. **The Execution (**`main`**):** * Instantiate a `Student` object. * Set the object's `name` attribute using `cin`. * Write a `for` loop that runs 3 times. Ask the user to input their recent mock scores for upcoming entrance exams (like JEE or BITSAT) and use `.push_back()` to add those scores directly into the object's vector. * Print a final statement showing the student's name and their average score by calling the object's `calculateAverage` method.

Write the class structure, instantiate the object, and drop your code below.

I got 91.56%ile in jee mains and was wondering whether I would get btech cse in jmi?

I want the normal cse but my rank is 1.3L(delhi hs) which guarantees USAR and gives slight chance at msit, so how's usar for cse or is it just for robotics?

i started 2 months back and thought of this small project of 2d grid games, please suggest improvements.

this was the question:

The Objective: Build a playable, interactive text-based survival game.

The Win Condition: The Player navigates a 5x5 map and collects 3 Data Cores before their HP hits 0.

The Mandatory Mechanics (Your Arsenal): You must utilize all of the following in your engine:

1. A 2D Array (char) to act as the map.
2. A Vector (std::vector) to act as the inventory for the Data Cores.
3. Pass-by-Reference (&) functions to handle player movement, map updates, and damage calculations.
4. A while loop to keep the game running until a win/loss condition is met.

That is it. You decide how it renders. You decide how the player inputs commands. You decide how the math works.

#include<iostream>
#include<vector>
#include <string>
using namespace std;


void renderMap(char map[5][5])
{
    for(int i = 0; i<=4; i++)
    {
        for(int j=0; j<=4; j++)
        {
            cout<<map[i][j]<<" ";
        }
        cout<<endl;
    }
}


void ProcessMove (char input, int& pRow, int& Pcol, int& hp ,vector <string>& inventory, char map[5][5],int prev_Prow, int prev_Pcol)
{
    prev_Prow = pRow;//storing column and row number of a the player in a variable to replace old position with "."
    prev_Pcol = Pcol;



    //UPDATION OF PCOL AND PROW NUMBER ALONG WITH POSITION
    if(input == 'W' && pRow!=0)
    {
        pRow = pRow - 1;
        map[prev_Prow][prev_Pcol] = '.';  //we replace "P" old place with "."
    }


    if(input=='A' && Pcol!=0)
    {
        Pcol = Pcol - 1;
        map[prev_Prow][prev_Pcol] = '.';  
    }


    if(input=='S' && pRow!=4)
    {
        pRow = pRow + 1;
        map[prev_Prow][prev_Pcol] = '.';  
    }


    if(input=='D' && Pcol!=4)
    {
        Pcol = Pcol + 1;
        map[prev_Prow][prev_Pcol] = '.';  



    }
    //scoring system
     if(map[pRow][Pcol]=='C')
        {
            inventory.push_back("CORE MAP ");
        }


    else if (map[pRow][Pcol]=='F')
        {
            hp = hp - 25;
        }


    //position update
    map[pRow][Pcol] = 'P';
    
}

I got 1.30L air in jee, online i found that msit cse closes at 1.37L , so is it a guarantee I can get msit?

I got 1.3 L in jee mains, I got 78.2% in boards and 77% aggregate in P and M. Can I get mait at 1.3 L cse with specialization?

The Scenario: You are building a Tetris clone or a top-down game. You have a 3x3 block (a 2D array of numbers). The player hits the "Rotate" button. You need to rotate the entire grid 90 degrees clockwise.

example:

starting->

1 2 3
4 5 6
7 8 9

after rotation->

7 4 1
8 5 2
9 6 3

this is a question gemini generated for me.
