Is there a way to check if any 4 strings out of 5 strings are equal? : I have 5 strings. 4 are the same, lets say they're all 'K' and one is different, 'J'. Is there a way to compare all of them and check if at least 4 out of the 5 are equal.

```
rc1 = 'K'
rc2 = 'J'
rc3 = 'K'
rc4 = 'K'
rc5 = 'K'

if four are the same from rc1, rc2, rc3, rc4 or rc5:
    print error
```
