[mai mult...]Check if all digits of a number divide it with Python3
Given a number n, find whether all digits of n divide it or not.
Examples:
Input : 128 Output : Yes 128 % 1 == 0, 128 % 2 == 0, and 128 % 8 == 0. Input : 130 Output : No
We want to test whether each digit is non-zero and divides the number. For example, with 128, we want to test d != 0 && 128 % d == 0 for d = 1, 2, 8. To do that, we need to iterate over each digit of the number.
[mai mult...]Python Script for Number of solutions to Modular Equations
Given A and B, the task is to find the number of possible values that X can take such that the given modular equation (A mod X) = B holds good. Here, X is also called a solution of the modular equation.
Examples:
Input : A = 26, B = 2
Output : 6
Explanation
X can be equal to any of {3, 4, 6, 8,
12, 24} as A modulus any of these values
equals 2 i. e., (26 mod 3) = (26 mod 4)
= (26 mod 6) = (26 mod 8) =Output:2
Input : 21 5
Output : 2
Explanation
X can be equal to any of {8, 16} as A modulus
any of these values equals 5 i.e. (21 mod
8) = (21 mod 16) = 5
