68: Write a program in C++ to find the sum of the series 1 + 1/2^2 + 1/3^3 + ..+ 1/n^n

// Write a program in C++ to find the sum of the series 1 + 1/2^2 + 1/3^3 + ..+ 1/n^n. Go to the editor

//     Sample Output:

//     Input the value for nth term: 5

//     1/1^1 = 1

//     1/2^2 = 0.25

//     1/3^3 = 0.037037

//     1/4^4 = 0.00390625

//     1/5^5 = 0.00032

//     The sum of the above series is: 1.29126
