1. Reverse a number (integer) by iterative program. Reverse a number: Input: prompt user to enter an integer. Output: print out the integer reversely. e. g.: if user enters 12345, your output will be 54321. 2. Reverse a number (integer) by recursive program. 3. ADT array-based polynomials a. Input/output Input: (1) The degree of the polynomial (the highest degree of all the terms in the polynomial) (2) The coefficient for each term from the highest degree to the lowest degree Output: Print out the polynomial. e. g.: if user enters 3 for the degree of the polynomial and enters 7, 0, 9, 10 for each term from the highest degree to the lowest degree, then the output will be: 7x^3 9x 10 b. Evaluation Once the polynomial has been entered by the user, prompt the user to enter the value of x and evaluate the polynomial and print out the value of the polynomial. e. g. if user enter 2 for the value of x (that is, x
