class Solution:
    def maxConsecutiveAnswers(self, answerKey: str, k: int) -> int:
        max_freq = i = 0
        d = {'T':0,'F':0}

        for j in range(len(answerKey)):
            d[answerKey[j]] += 1

            max_freq = max(max_freq,d[answerKey[j]])

            if(j-i+1>max_freq+k):
                d[answerKey[i]] -= 1
                i+=1

        return len(answerKey)-i
