a) Write a program that prompts for an integer-let's call it X-and then finds the sum of X consecutive integers starting at 1. That is, if X=5, you will find the sum of 1+2+3+4+5=15. b) Modify your program by enclosing your loop in another loop so that you can find consecutive sums. For example, if 5 is entered, you will find five sum of consecutive numbers:1 = 11+2 = 31+2+3 = 61+2+3+4 = 101+2+3+4+5 = 15Print only each sum, not the arithmetic expression.

Solution a

n = int (input ("Enter an integer: ")) sum = 0 for x in range (1, n+1) : sum + = x print (sum)

Solution b

n = int (input ("Enter an integer: ")) for a in range (1, n + 1) : sum = 0 for x in range (1, a+1) : sum + = x print (sum)

Explanation:

Solution code is written in Python 3.

Solution a

First get the user input for an integer (Line 1).

Create a variable sum and initialize it with zero value (Line 3).

Create a for loop to traverse through the number from 1 to integer n (inclusive) and sum up the current number x (Line 5-6).

Print the sum to terminal (Line 8).

Solution b

Create an outer for loop that traverse through the number from 1 to integer n (inclusive) (Line 3).

Create an inner loop that traverse through the number from 1 to current a value from the outer loop and sum up the current x value (Line 5-6).

Print the sum to terminal (Line 7) and proceed to next iteration and reset the sum to zero (Line 4).
