Check if given four integers (or sides) make rectangle
  • Difficulty Level : Basic
  • Last Updated : 08 Apr, 2021

Given four positive integers, determine if there’s a rectangle such that the lengths of its sides are a, b, c and d (in any order).
Examples : 
 

Input : 1 1 2 2
Output : Yes

Input : 1 2 3 4
Output : No

Approach 1 :- We will check, if any of the two integers are equal and make sure rest of two are also equal using few if else conditions. 
 

C++




// A simple program to find if given 4
// values can represent 4 sides of rectangle
#include <iostream>
using namespace std;
 
// Function to check if the given
// integers value make a rectangle
bool isRectangle(int a, int b, int c, int d)
{
    // Square is also a rectangle
    if (a == b == c == d)
        return true;
 
    else if (a == b && c == d)
        return true;
    else if (a == d && c == b)
        return true;
    else if (a == c && d == b)
        return true;
    else
        return false;
}
 
// Driver code
int main()
{
    int a, b, c, d;
    a = 1, b = 2, c = 3, d = 4;
    if (isRectangle(a, b, c, d))
        cout << "Yes";
    else
        cout << "No";
    return 0;
}

Java




// A simple program to find if
// given 4 values can represent
// 4 sides of rectangle
class GFG {
 
    // Function to check if the given
    // integers value make a rectangle
    static boolean isRectangle(int a, int b,
                               int c, int d)
    {
        // Square is also a rectangle
        if (a == b && a == c &&
            a == d && c == d &&
            b == c && b == d)
            return true;
     
        else if (a == b && c == d)
            return true;
        else if (a == d && c == b)
            return true;
        else if (a == c && d == b)
            return true;
        else
            return false;
    }
     
    // Driver code
    public static void main(String[] args)
    {
         
        int a = 1, b = 2, c = 3, d = 4;
        if (isRectangle(a, b, c, d))
            System.out.println("Yes");
        else
            System.out.println("No");
    }
}

        else
            return false;
    }
 
// Driver code
 
        let a = 1, b = 2, c = 3, d = 4;
        if (isRectangle(a, b, c, d))
            document.write("Yes");
        else
            document.write("No");
            
</script>

Output : 

No
