Inverse function in programming refers to the relationship between one function and another function that are the inverse operations of each other. In other words, if function A maps input x to output y, then function B maps input y back to output x. In this article, we will explore how to implement the inverse function in programming and provide corresponding source code examples.
First, let's define a simple function that doubles an integer:
def double(x):
return x * 2
Now, we want to implement an inverse function that restores the doubled integer to its original value. To do this, we can write a function that divides the input value by 2:
def half(y):
return y /<
