Question

Write a python function Summation(n) that takes a number n as a parameter
and print out the integers from 1 to n and also print out the calculated summation as follows:

Test Runs for Question #2:

Summation(1)
1 = 1

Summation(3)
1 = 1
1 + 2 = 3
1 + 2 + 3 = 6

Summation(10)
1 = 1
1 + 2 = 3
1 + 2 + 3 = 6
1 + 2 + 3 + 4 = 10
1 + 2 + 3 + 4 + 5 = 15
1 + 2 + 3 + 4 + 5 + 6 = 21
1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55

Expert Solution

Step 1

The function to print summation can be created as follows:

Two loops will be used. The outer loop is for printing the sum of numbers 1 to n. The inner loop is for printing the numbers from 1 to n.
Inside the outer loop, declare a variable to store the sum of current 1 to n.
The inner loop will print the numbers and add the numbers to the variable.
After exiting the inner loop, the sum will be created.
