Please Here the problem statement from leetcode. At the end, if we are in state read As or read Bs, we return true. No description, website, or topics provided. Example 1: Input: s = "aaabbb" Output: true Explanation: The 'a's are at indices 0, 1, and 2, while the 'b's are at indices 3, 4, and 5. When we encounter the first b, we change the our state, so that we can only see Bs from now on. Given a string s consisting of only the characters 'a' and 'b', return true if every 'a' appears before every 'b' in the string. Work fast with our official CLI. After first index of b there should not be any index after which a should be present. Here the problem statement from leetcode. If we encounter an a after we have already seen a b, we return false. You can show support by following me on medium. If we finish the string without having returned false, we return true. Otherwise, return "aaa" => true"bbb" => true"" => true"ba" => false"aababb" => false To solve the.
