Write the function which takes an arbitrary real number p , and returns true if the numeber is equals to some power of 2, i. e. p=2n for some n . Your task is to implement a recursive function power_of_2 withount using loops and library functions.

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits. now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order. finally, output thedigits in thearray. use at least two functions to organize your program.
