Web20 feb. 2024 · If we look carefully, all the divisors are present in pairs. For example if n = 100, then the various pairs of divisors are: (1,100), (2,50), (4,25), (5,20), (10,10) Using this fact we could speed up our program significantly. We, however, have to be careful if there are two equal divisors as in the case of (10, 10). Web12 jun. 2024 · The problem asks to calculate the number of elements of an array that are not divisors of each element.
