Idempotence

Idempotence is a property of certain operations in mathematics and computer science where applying the operation multiple times has the same effect as applying it just once. In other words, performing an operation a number of times doesn't change the result beyond the initial application. ### Mathematical Definition In mathematics, a function \( f \) is considered idempotent if: \[ f(f(x)) = f(x) \quad \text{for all } x \] ### Examples 1.
