Construct a Valid Taco String

Given a positive integer \( n \), your task is to construct a string of length \( n \) using only the characters 'a', 'b', and 'c'.

The generated string must satisfy the following conditions:

• No two consecutive 'b' characters appear (i.e. the substring "bb" is forbidden).
• The string does not contain the substrings \( abc \) or \( cba \) anywhere.

You may output any valid string that meets these constraints.

inputFormat

The input consists of a single positive integer \( n \) provided via standard input (stdin), which specifies the required length of the string.

outputFormat

Output a valid string of exactly \( n \) characters to standard output (stdout) using only the characters 'a', 'b', and 'c'. The string must satisfy the following:

• No two consecutive 'b' characters.
• It must not contain the substrings \( abc \) or \( cba \).
