p00053 Sum of Prime Numbers
Let p (i) be the i-th prime number from the smallest. For example, 7 is the fourth prime number from the smallest, 2, 3, 5, 7, so p (4) = 7. Given n, the sum of p (i) from i = 1 to n s s = p (1) + p (2) + .... + p (n) Create a program that outputs. For example, when n = 9, s = 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 ...

Let p (i) be the i-th prime number from the smallest. For example, 7 is the fourth prime number from the smallest, 2, 3, 5, 7, so p (4) = 7. Given n, the sum of p (i) from i = 1 to n s s = p (1) + p (2) + .... + p (n) Create a program that outputs. For example, when n = 9, s = 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 ...
