I am getting wrong ans on test case 8 which is very big , I am not able to find any left case in my code.
please help Thanks in advance
why do you think the middlemost character will be your answer ?
for example
aaabbbccba
I am not taking the middle most character of original string
I am taking the middle character of unique of original string
like for your test case aaabbbccba so we should take c and insert it at 3 possible places to remove the complete string
my s1(unique of s) will be abcba and then I am taking center of this which will be c
so my code will give ans as 3 for this test case
ok my bad
Check this
bbbaaabbab
