In C++

Both images below are under the same number (1a and 1b)

Please provide code for whole program and function only to both 1a and 1b.

tere's an example: threeNPlus1(13) will return 10 since the sequence obtained from 13 is which has length 10. Inother example: threeNPlus1(27) return 112 since the sequence obtained from 27 is hich has length 112. TW The Collatz conjecture says that any starting value of n will eventually lead to a final value of 1 . So far nobody has been able to prove this
