Problem Statement – An automobile company manufactures both a two wheeler (TW) and a four wheeler (FW). A company manager wants to make the production of both types of vehicle according to the given data below:

1st data, Total number of vehicle (two-wheeler + four-wheeler)=v
2nd data, Total number of wheels = W

The task is to find how many two-wheelers as well as four-wheelers need to manufacture as per the given data.

Example :

Input :

200 -> Value of V
540 -> Value of W

Output :

TW =130 FW=70

Explanation:

130+70 = 200 vehicles

(70*4)+(130*2)= 540 wheels

Constraints :

2<=W
W%2=0
V<W

Print “INVALID INPUT” , if inputs did not meet the constraints.

The input format for testing

The candidate has to write the code to accept two positive numbers separated by a new line.

First Input line – Accept value of V.
Second Input line- Accept value for W.

The output format for testing

Written program code should generate two outputs, each separated by a single space character(see the example)
Additional messages in the output will result in the failure of test case

Solution

C++

#include <bits/stdc++.h>
using namespace std;

 
int main () 
{
  int v, w;
  cin >> v >> w;
  float x = ((4 * v) - w) / 2;
  if ((w & 1) || w < 2 || w <= v)
    {
      cout << "INVALID INPUT";
      return 0;
    }
cout << "TW=" << x << " " << "FW=" << v - x;

}

Java

import java.util.*;
public class Solution
{
    public static void main(String[] args)
    {
             Scanner sc=new Scanner(System.in);
             int v=sc.nextInt();
             int w=sc.nextInt();
             float res=((4*v)-w)/2;
             if(w>=2 && (w%2==0) && v<w ) 
               System.out.println("TW= "+(int)(res)+" FW= "+(int)(v-res));
             else
                System.out.println("INVALID INPUT");
    }
}

Python

v=int(input())
w=int(input())
if (w&1)==1 or w<2 or w<=v:
    print("INVALID INPUT")
else:
    x=((4*v) -w)//2
    print("TW={0} FW={1}".format(x,v-x))
