This function uses recursion to check if a number can be constructed starting with 3 using only the operations of ! (factorial), sqrt() and floor(). It first checks if the number is 0 or 1, in which case it returns True. Then it checks if the number is even or odd, in which cas...
Factorial Using RecursionRecursive functions are very useful to solve many mathematical problems such as calculating the factorial of a number, generating Fibonacci series, etc.The most popular example of recursion is calculation of factorial. Mathematically, a factorial is defined as −...
