Memorizing important algorithms such as binary search

algorithm

Solution

Its always better to find ways to understand the underlying principle of such algorithms rather than memorizing them. For example - Quick Sort uses Divide and Conquer paradigm (it is a design technique to solve a certain class of problems).

Wiki is a very good starting point to dissect a new topic. You can dig deep by watching video lectures (found this good post on Video Lectures here on SO) and other specific material such as concerned research papers.

Working out examples will also clarify the algorithm better.

I hope this helps.
