Check if given four integers (or sides) make rectangle

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
```

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

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 ` `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; ` `} `
