Answer 1

function find_longest_repeating_character(str) {
    let longest_count = 0;
    let size = str.length;
    let longest_repeating_character = ' ';
    
    for (let i = 0; i < size; ) {
        let ch = str.charAt(i);
        let count = 0;
        for (; i < size && ch == str.charAt(i); i++) {
            count++;
        }
        if (count > longest_count) {
            longest_count = count;
            longest_repeating_character = ch;
        }
    }
    return longest_repeating_character;
}
