Programming Topics:

Time complexity

space complexity

Recursion: -

    Break down a complex problem into simpler versions of the problem itself.

    ex. Factorial, Fibonacci series

    4! = 4 * 3!

    3! = 3 * 2!

Python notes - useful/handy libraries commands or features -

#set recursion limit -

import sys 

# the setrecursionlimit function is  used to modify the default recursion  limit set by python. Using this,  we can increase the recursion limit to satisfy our needs !

sys.setrecursionlimit(10**6)
