Perfect Square Without Libraries | Dataford Interview Questions

Given an array of integers, write an algorithm to detect if a specific number is a perfect square without using built-in library functions.

Implement the function for one supplied integer. Return True if it is the square of an integer and False otherwise. Do not use square-root, power, or equivalent library functions; avoid floating-point arithmetic.

Constraints

-10^9 <= num <= 10^9
Do not use square-root, power, or equivalent library functions
The result must be based on integer arithmetic

Function Signature
