Is recursion a declarative approach to solve the problems?
I have noticed many problems in algorithms textbook are solved by recursion (divide and conquer, backtracking,…)

Is there a (systematic) way to convert a recursive program to a version using user stack?
I have an image (an array of 1000 x 1000 pixels) of 1s and 0s. I was asked to do edge detection, so I wrote this program in C to traverse the figure. My idea was to convert every pixel surrounded by like pixels to white (1) and every pixel surrounded by at least one unlike pixel to black (0). And I used recursion.
Why does this recursion method work? I have explored it for a day or two, and I cannot figure out why
Problem Statement:
Trouble understanding simple recursion in c [duplicate]
This question already has answers here: In plain English, what is recursion? (18 answers) Closed 9 years ago. My function: int num(int x) { if(x>0) num(x-1); else return 0; printf(“%d”,x); } This function takes a input x and prints the numbers from 1 upto x.I can’t seem to understand how this works, can someone please […]
Given a tree calculating Max Sum from top to bottom suing DFS? optimization?
given a tree i want to calculate max sum of each path from top to bottom. I used DFS for the operation. Here is the function which takes root as input and gives max sum of the path from top to bottom :
