How I'll memorize a lot of algorithm by data structure programming ?

Answer 1

Code the algorithm over and over and over again. Select like 3 different algorithms and go over each of them, until you can code the whole thing without consulting some other source. At the point, you will know the algorithm in and out.

Answer 2

Don't try to memorize anything, it will never work.
Instead try to understand it, then it will always be there when you need to access it
