Write a program that computes the summation between 1 and a given number. For example, if the user inputs 5 the function should add 1 + 2 + 3 + 4 + 5, and return 15. The program should compute the summation in two different ways which are described bellow and compare if the functions produce the same result. 1. Write a function that computes the summation between 1 and a given number using a loop. 2. Write a function that computes the summation between 1 and a given number n using the following formula: sigma^n_i = 1 n * (n + 1)/2 Example of program execution: Input a number. .. 5 Using a loop the result of the summation is 15 Using Gausss formula, the result of the summation is 15 Both methods give the same
