 ### Factorial
 - [FactRecursion](factRecursion.cpp)
-FactRecursion, which is a program for factorial of a number. Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example, we can think of factorial 5 is = 5x4x3x2x1 = 120
-Time complexity => O(n)
