  Learn Tech Skills from Scratch @ Scaler EDGE # Is Rectangle?

Problem Description

Given four positive integers A, B, C, D, determine if there’s a rectangle such that the lengths of its sides are A, B, C and D (in any order).

If any such rectangle exist return 1 else return 0.

Problem Constraints

1 <= A, B, C, D <= 100

Input Format

First argument is an interger A.

Second argument is an interger B.

Third argument is an interger C.

Fourth argument is an interger D.

Output Format

If any such rectangle exist whose sides are A, B, C, D in any orde then return 1 else return 0.

Example Input

Input 1:

``` A = 1
B = 1
C = 2
D = 2
```

Input 2:

``` A = 1
B = 2
C = 3
D = 4
```

Example Output

Output 1:

``` 1
```

Output 2:

``` 0
```

Example Explanation

Explanation 1:

``` The rectangle drawn above is one of the rectangles that can be formed by side length of 1, 1, 2, 2 so we will return 1.
```

Explanation 2:

``` No such rectangle exist whose sides are 1, 2, 3, 4. So, we will return 0.
```
