Can you help me pass all test cases

hello @manav_sharma

ur approach is not correct.

here u need to find the maximum length of a substring (consecutive subsequence) consisting of equal letters. and u are allowed to change no more than k characters of the original string.

for example->
4 2
abba

answer is 4 becuase can obtain both strings “aaaa”(by change 2 b’s into a) and “bbbb”(changing a’ to b)

8 1
aabaabaa
answer is 5 becuase we can obtain string “aaaaabaa” or string “aabaaaaa”. (both have 5 length substring with all smae character)

hint -> two pointers
