Perfect Cube Implementation

[octavianarmasu]

Description

The perfect cube function provides two functions to check if a given number is a perfect cube.

perfect_cube(n: i32) -> bool

• Checks if a number is a perfect cube using floating-point arithmetic.
• Calculates the cube root of the given number and checks if cubing it equals the original number.

perfect_cube_binary_search(n: i64) -> bool

• Checks if a number is a perfect cube using binary search.
• Handles negative numbers by returning false for negative inputs.
• Performs a binary search to find the cube root within the range [0, abs(n)].
