Add each element in origList with the corresponding value in offsetAmount. Print each sum followed by a space. Ex: If origList = {40, 50, 60, 70} and offsetAmount = {5, 7, 3, 0}, print: 

45 57 63 70

Sum of the series

Write a program to find the sum

S of the series where S = x - x^3 + x^5 + ....... upto N terms.

Sample Input 1

2

5

Sample Output 1

410

to solve this approch

if i value is even:

result = summation of the term value and then added to the result

else :

result = Subtraction of the term value and then added to the result
