The Echo Chamber

In a mystical canyon, every word you shout echoes back, but each echo loses its first character and repeats until either the word is empty or it has echoed N times. Given a word and a number N, print the original word followed by its echoes on a single line, separated by spaces. Input Format: A single line containing a string S and an integer N separated by a space. Output Format: A single line containing the sequence of strings. Example: Input: HELLO 3 Output: HELLO ELLO LLO
