Cars and Bikes Problem Code: TYRES | CodeChef

Problem:

Chef opened a company which manufactures cars and bikes. Each car requires 

4 tyres while each bike requires 2 tyres. Chef has a total of N tyres (N is even). He wants to manufacture maximum number of cars from these tyres and then manufacture bikes from the remaining tyres.

Chef's friend went to Chef to purchase a bike. If Chef's company has manufactured even a single bike then Chef's friend will be able to purchase it.

Determine whether he will be able to purchase the bike or not.

Input Format

  • The first line contains an integer T denoting the number of test cases. The T test cases then follow.
  • The first line of each test case contains an integer N denoting the number of tyres.

Output Format

For each test case, output YES or NO depending on whether Chef's friend will be able to purchase the bike or not. Output is case insensitive.

Constraints

  • 1T100
  • 2N1000
  • N is even

Sample Input 1 

3
8
2
6

Sample Output 1 

NO
YES
YES

Explanation

  • For the first test case Chef, will manufacture 2 cars and will thus use all the 8 tyres and thus could not manufacture any bike.

  • For the second test case, Chef cannot manufacture any car since there are not enough tyres and will thus manufacture only a single bike which will be purchased by Chef's friend.

  • For the third test case, Chef will manufacture 1 car and thus use 4 tyres. From the remaining 2 tyres, Chef can manufacture a single bike which will be purchased by Chef's friend.

Solution:

#include <iostream>
using namespace std;

int main() {
// your code goes here
int t; cin>>t;
while(t--){
    int n;cin>>n;
    while(n>4){
        n%=4;
    }
    if(n>=2 && n%2==0)
        cout<<"YES"<<endl;
   else cout<<"NO"<<endl;
}
return 0;
}

Java Flow Control And Functions If Else | Day 1

Problem: In computer programming, we use the if statement to control the flow of the program. For example, if a certain condition is met, then run a specific block of code. Otherwise, run another code. For example: class Main { public static void main(String[] args) { int number = 0; // checks if number is greater than 0 if (number > 0) { System.out.println("The number is positive."); } // checks if number is less than 0 else if (number < 0) { System.out.println("The number is negative."); } // if both condition is false else { System.out.println("The number is 0."); } } } Output The number is 0. In the above example, we are checking whether the  number is positive, negative, or zero . Here, we have two condition expressions: number > 0  - checks if the number is greater than 0 number < 0  - checks if the number is less than 0 Here, the value of the  number is 0 . So both th...
