can anyone tell me what is wrong with this solution ?

Here’s a few failing testcases:

```
1
10000 10000 9000 9000
```

```
1
10000 10000 10000 10000
```

```
1
2 6 3 4
```

Here’s a solution. The logic is that there should be a pair of pairs of sides that bear equal values each.

ok the last case

1

2 6 3 4

proves this approach is wrong

i was also thinking about such pair where there is chance of being perfect square not being equal ,thanks for the help

gotcha
