Magic String Generator

You are given an integer n. Your task is to create a magic string of length n by repeating the cycle of characters abc. Specifically, when n satisfies the condition $$1 \le n \le 100000$$, the magic string is obtained by repeating the sequence "abc" until the length reaches at least n and then taking the first n characters. If n does not meet the condition, print NO.

If a valid magic string can be generated, output two lines. The first line must contain YES and the second line the magic string. Otherwise, print only NO on a single line.

inputFormat

The input is read from standard input and consists of a single integer n in one line.

outputFormat

If n is valid (i.e. $$1 \le n \le 100000$$), the output should be two lines: the first line with YES and the second line with the generated magic string of length n. Otherwise, output NO on a single line.
