Just saw a Circle of numbers on my Whats App message (source not listed) which is as following
Arrange numbers 1 to 32 in a circle such that any two adjacent (neighboring) numbers add up to a perfect square (like 1,4,9,16 etc). No number can be repeated.
Without programing you can try that and get an answer.
There is a question on this site
That puts 14 numbers around a circle where either the sum or the absolute difference between the neigboring numbers is a Prime number
Here is my question
Can you put numbers 1 to 32 (without repeating any number) in a circle such that the sum of the neighboring numbers is a Prime Number?
So if any three numbers (clockwise or anti clockwise) are a,b and c then a+b and b+c must be a Prime. and so on.
You can either answer my question OR both the WhatsApp and my question together.
There may be more than one answer.
