You are given a positive integer n.

\n\n

Continuously replace n with the sum of its prime factors.

\n\n\n\n

Return the smallest value n will take on.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = 15\nOutput: 5\nExplanation: Initially, n = 15.\n15 = 3 * 5, so replace n with 3 + 5 = 8.\n8 = 2 * 2 * 2, so replace n with 2 + 2 + 2 = 6.\n6 = 2 * 3, so replace n with 2 + 3 = 5.\n5 is the smallest value n will take on.\n
\n\n

Example 2:

\n\n
\nInput: n = 3\nOutput: 3\nExplanation: Initially, n = 3.\n3 is the smallest value n will take on.\n
