Help me write an extreme average filter program

I can provide you with a sample code for an extremal averaging filter: int n = 5; int sum = 0; int[] values ​​= { 10, 20, 30, 15, 25 }; for (int i = 0; i < n; i++) { sum += values[i]; }int average = sum / n; for (int i = 0; i < n; i++) { values[i] = max(values[i], average ); }
