Web29 sep. 2024 · The Quicksort is also one of the best examples of recursion, a key programming technique to solve Algorithmic problems. This algorithm is naturally recursive because it sorts the large list by dividing it into smaller sub-list and then applying the same algorithm to those. WebBut for each recursive call, the algorithm needs to use or maintain the stack to store some amount of data. Now, what is space complexity behind it and it depends on what is the depth of stack use. Now the depth of the stack is height of the tree. So, if the tree is a balanced tree then we know level of the tree is log n.

WebIn this problem, we will discuss the combinations of alphabets that occurred by pressing the numbers on the phone keypad, and this problem is solved in C++. Approach:-It is often determined that every digit will represent three to four totally different alphabets (apart from zero and 1). Therefore the plan is to make a Recursive function.
