Problem 552
Posted: Mon Dec 06, 2021 11:28 am
I know the example clear shows that A1 (=3) is not counted into the sum S(N), but should it be?
I reckon A1 = 1, since it is the smallest positive integer satisfying A1==1 mod 2.SaxTenor wrote: Mon Dec 06, 2021 11:28 am I know the example clear shows that A1 (=3) is not counted into the sum S(N), but should it be?
