{'T', 'a', 'b', 'l', 'e'}, 'P' {'T', 'P', 'a', 'P', 'b', 'P', 'l', 'P', 'e', 'P'}

class SuffixEveryCharacterInArray
    public static void main(String s[])
        char input[] = {'B', 'o', 'o', 'k'};
        char result[] = suffixEveryCharacter(input, 'T');
        System.out.print("After suffixing every character in the input word : ");
        for (char ch : result)
        System.out.print(ch + " ");
