Problem Statement of String Without AAA or BBB

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.

Complexity Analysis

• Time Complexity: O(n)
• Space Complexity: O(n)

984. String Without AAA or BBB LeetCode Solution in C++

class Solution {
 public:
  string strWithout3a3b(int A, int B, char a = 'a', char b = 'b') {
    if (A < B)
      return strWithout3a3b(B, A, b, a);
    if (B == 0)
      return string(min(A, 2), a);

    const int useA = min(A, 2);
    const int useB = (A - useA >= B) ? 1 : 0;
    return string(useA, a) + string(useB, b) +
           strWithout3a3b(A - useA, B - useB, a, b);
  }
