Recursion & Iteration  (Video Here)   Recursion and iteration both repeatedly executes the set of instructions. Recursion is when a statement in a function calls itself repeatedly. The iteration is when a loop repeatedly executes until the controlling condition becomes false. The primary difference between recursion and iteration is that is a  recursion  is a process, always applied to a function. The  iteration  is applied to the set of instructions which we want to get repeatedly executed. // C++ program to find factorial of given number #include<bits/stdc++.h> using namespace std;     // ----- Recursion ----- // method to find factorial of given number int factorialUsingRecursion( int n) {      if (n == 0)          return 1;          // recursion call      return n * factorialUsingRecu...
