Given two integers a and b, return any string s such that:

  • s has length a + b and contains exactly a 'a' letters, and exactly b 'b' letters,
  • The substring 'aaa' does not occur in s, and
  • The substring 'bbb' does not occur in s.

 

Example 1:

Input: a = 1, b = 2
Output: "abb"
Explanation: "abb", "bab" and "bba" are all correct answers.

Example 2:

Input: a = 4, b = 1
Output: "aabaa"

 

Constraints:

  • 0 <= a, b <= 100
  • It is guaranteed such an s exists for the given a and b.
