Minimum primes
{Draft task}}
- Task
Given three lists:
- Numbers1 = [5,45,23,21,67]
- Numbers2 = [43,22,78,46,38]
- Numbers3 = [9,98,12,54,53]
then:
- Select the maximum (max) of Numbers[n], Numbers2[n] and Numbers3[n], where n <= 5 (one based).
- Select minPrime for that minPrime is prime and minPrime <= max
- Add minPrime to a new list (Primes)
- Show Primes on this page.
