What is recursion and when should I use it? - Stack Overflow

WebHere is the basic idea behind recursive algorithms: To solve a problem, solve a subproblem that is a smaller instance of the same problem, and then use the solution to that smaller instance to solve the original problem. WebSince there are usually only two main conditions in a recursive function ( 1 - base case met, 2 - base case not met) it is only logical to only have two condition checks. The if checks for the base case, if the base case has not been reached else does calculations and sends …

Web1.2 Recursion tree A recursion tree is a tree where each node represents the cost of a certain recursive sub-problem. Then you can sum up the numbers in each node to get the cost of the entire algorithm. Note: We would usually use a recursion tree to generate possible guesses for the runtime, and then use the substitution method to prove them.
