TLE hack
By _punk, history, 6 years ago, In English

whenever you are doing a question in which addition to a string requires , that is , we have to add an character into a string or we have to insert into a stack. Then instead of using '+' operator go for push_back. this help in lot of questions where you are doing a lot of '+' operation in a string. i got this when i was solving a question on geeks and i found TLE many times. Then I tried roughly push_back, and BOOM it worked XD. Thats where i learnt when you are not getting your answer when you are right , then go for rough guesses.

HAPPY CODING :)

You can use += also. This hack allows you to add a string to the right for O(the length of the string wich you want to add). For example, a += b working for O( len(b) )

      Sure. But the way you wrote your post tells me that you don't have a very good grasp in C++ like many others who just code blindly without reading the STL docs.
