Perfect Square

Detailed guide and Python implementation for the 'Perfect Square' problem.

問題提起

簡単

Write a function is_perfect_square(n) that takes a non-negative integer n and returns True if n is a perfect square, or False otherwise. A perfect square is an integer that is the square of some integer (e.g., 0, 1, 4, 9, 16, ...).

制約
  • 0 <= n <= 10^9

Example 1
Input
n = 16
Output
True
Explanation

16 = 4 × 4, so it is a perfect square.

Example 2
Input
n = 14
Output
False
Explanation

There is no integer whose square is 14.

Example 3
Input
n = 0
Output
True
Explanation

0 = 0 × 0, so it is a perfect square.

Consider using Basics-specific data structures like sets or heaps.
Edge Cases to Watch
  • Empty input structures
  • Single element inputs
  • Large numerical bounds
