    for (int i = 0; i < str.length - 1; i++) {
        for (int j = i + 1; j < str.length; j++) {
            if (str[i] == str[j]) {
                int temp = (j - i - 1).abs();
                maxCh = maxCh > temp ? maxCh : temp;
            }
        }
    }
    
    return maxCh;

void main() {
    String str = "aBcaaBdefBgh";
