I’ve checked the forums and still no clue as to what’s wrong. I’m using C++.

Thanks!

a.resize(25000);
 b.resize(25000);

Keep string size atleast 1 more than the maximum size possible in constraint, to allow for “\0” character.

Additionally, your code fails for such cases-

Input
1
zzzzz xxxxzx
Your Output
YES
Expected Output
NO //Since neither is a subsequence of another- 2nd string needs more z i believe.

This error is because, you are deleting string b from index[0,4] only, while z occurs at index 5. So this z is available to satisfy all other z in string a. Meaning, check the upper limit of your deletion function. Its 1 index less than needed.

Wow. This forum is really responsive.

Thanks a lot vijju123. I had misunderstood string.erase() when used with iterators. Only had to add +1 and got AC :))
