CalculatePower.java

// Calculate Power
// Send Feedback
// Write a program to find x to the power n (i.e. x^n). Take x and n from the user. You need to return the answer.
// Do this recursively.
// Input format :
// Two integers x and n (separated by space)
// Output Format :
// x^n (i.e. x raise to the power n)
// Constraints :
// 0 <= x <= 30
// 0 <= n <= 30
// Sample Input 1 :
//  3 4
// Sample Output 1 :
// 81
// Sample Input 2 :
//  2 5
// Sample Output 2 :
// 32
