6. Write a program to compute the sum of the terms of the series: 1 + 2 + 4 + 8 + 16 + 32+64 +n, where n is an input. Consider that n is always valid (which means it follows the series pattern). For example, if n- 256, the program sums 12 +4+ 8 + 16 + 32 + 64 + 128 256 and displays the result 511. 1Enter the value of n: 32 3 The sum is 63 1 Enter the value of n 512 3 The sum is 1023
