If we do in the divisor_sum function, that run the loop from i=1 to i<=sqrt(num), then also it should print the same, So what is wrong in this one? Because doing so it is printing only 1 as output. Please Do resolve this as well.

#6

Get this with an example, 28 is perfect number. Sqrt(28) will be 5, whereas when you will find divisor of 28, they will be 2,2,7. So 7 won’t be included while running the loop. Same is for 6, sqrt(6) will be 2. So 3 won’t be included. So it won’t work.
