Question

5.Write pseudocode for the algorithm using iteration (looping) and make a flow chart and python code from your pseudocode.

Envision an algorithm that when given any positive integer n, it will print out the sum of the squares from 1 to n. For example given 3 the algorithm will print 14 (because 1 + 4 + 9 =14) You can use multiplication denoted as * in your solution and you do not have to define it (For example. 3*3=9) For example if n is 6 it will print: The sum of squares from 1 to 6 = 91 Again, to get marks, the algorithm needs to work for any n given.

Answer 1

PSEUDOCODE ::

Input the positive integer n

k=n , sum = 0

while n>0

sum = sum +(n*n)

n=n-1

Print : The sum of squares from 1 to k = sum

PYTHON CODE :

# To take the desired integer as input

n=int(input())

# initialising the value to 0
sum = 0

# stored the value of n in another variable
k=n

# checking whether n is > 0 or not
while(n > 0) :
sum=sum+(n*n) # adding square of the present value of n to sum
n=n-1 # decrement the value of n

# printing the output
print('The sum of squares from 1 to {0} = {1}'.format(k, sum))
