Project Euler -- 48 (Self powers)

Problem : The series, 1¹ + 2² + 3³ + ... + 10¹⁰ = 10405071317.

Find the last ten digits of the series, 1¹ + 2² + 3³ + ... + 1000¹⁰⁰⁰.

My solution approach is,

first made a smaller version of the problem then I tried to solve it after solving this I was going to solve the bigger version.

// a. find out p=2^15

// b. print the last digit of p
