How to get rid of TLE in Java

Question

I was taking a test, the question asked was to rotate an array by some value provided by user. The user input consisted of number of test cases and in second line length of array and rotate point.

Eg:

1
5 3
1 2 3 4 5
Output
4 5 1 2 3

I have written the program and got the correct answer also but then again I am getting TLE when I submitted the code. Please help me understand what is this TLE and how to get rid of it?

 

Answer 1

The TLE (Time limit exceed) problem occurs due to the time taken by Java to take input and write output using Scanner class which is slow. I know of the two ways and that works absolutely fine.

1. Avoid using Scanner Class and try to use BufferedReader class.
2. Try to use StringBuffer class in case you have to print large number of data.
