Your solutions give wrong answer to almost all the test cases.

example:

input

2

abbaabbacaacfguiuoppo

your output is 0 while correct answer is 5

input

3

abbbaaabbbbaaaaaabbbbbbbbbbbbbbbbbaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbb

your output is 10 while correct answer is 65.

input

2

aaaaa

your output is 2 while correct answer is 4.

hope it help to find bug in your program.

enjoy happy coding

My code gives the correct answer for the all testcases mentionend above but it’s still wa

What logical mistake did I make?

Thanks in advance!

I did not use Manacher’s Algorithm, instead I used Rabin Karp.

thanks… after little modification got AC…
