The problem
This operate ought to take a look at if the issue is an element of base.
Return true if it’s a issue or false if it isn’t.
About components
Components are numbers you may multiply collectively to get one other quantity.
2 and three are components of 6 as a result of: 2 * 3 = 6
- You will discover an element by dividing numbers. If the rest is 0 then the quantity is an element.
- You should use the mod operator (
%) in most languages to test for a the rest
Examples:
2 isn’t an element of seven as a result of: 7 % 2 = 1
Notice: base is a non-negative quantity, issue is a constructive quantity.
The answer in Python
Choice 1:
def check_for_factor(base, issue):
return base/issue == int(base/issue)
Choice 2:
def check_for_factor(base, issue):
return base % issue == 0
Choice 3:
check_for_factor=lambda a,b:not apercentb
