There are several anomalies/bugs in your code.

first of all, the if condition is wrong and should never be written in the way you wrote..

Code: Select all

if((st[i-1]==st[i-2]&&i>=2)||(st[i-1]==st[i+1]&&i<len-1)){acc = 0;break;}

it should be..

Code: Select all

if((i >= 2 && st[i - 1] == st[i - 2]) || (i < len - 1 && st[i - 1] == st[i + 1]))...

what i want to say is the boundary condition i >= 2 or i < len - 1 must be checked first and then array accessing..

and i think your code will fail in the following input..
bcda

it prints bcda is acceptable but its not..

hope this helps..
