Add Analysis of Algorithms present in Repository

[sirjan13]

I have been contributing to this repository and I feel adding Comments mentioning TIme Complexity will be really beneficial for those who would refer to this repository.

Format for adding comments to the respective codes:

Eg:

For Binary Search:-

Time Complexity : O(logn)

@srbcheema1 it would be great if you could review this and add this under the appropriate labels so that contributors can work towards it.

thanks for creating the issue @sirjan13
also i would like to add some rules for codes like code must be modular (functions for different tasks)
and also there should be proper commenting
if there is an alternative way of solving same problem then you can also add all the solutions to a folder
segmented tree problems can be solved with binary indexed tree

@sirjan13
you may provide a set of standard rules to follow to create an analysis

I Think mentioning Time Complexity is a good way.
