This PR adds the Python implementation for the LeetCode 1941 problem — "Check if All Characters Have Equal Number of Occurrences".
The solution determines whether every character in a string appears the same number of times.

Key Details:

Algorithm Used: Frequency Counting using collections.Counter

Time Complexity: O(n)

Space Complexity: O(k), where k is the number of unique characters

Approach:

Count occurrences of each character using Counter.

Convert all frequency values into a set.

If the length of this set equals 1, it means all counts are identical.

Files Added:

are_string_occurrences_equal.py → Main implementation with docstrings and sample runs.

💎 Code Quality Check Results

❌ Missing Algorithm Description

These files don't explain what the algorithm does:

  • Python/algorithms/string_algorithms/are_string_occurences_equal.py

Required: Add a description explaining the algorithm, its purpose, and how it works

📚 Quality Standards

To maintain high quality, every contribution should include:

  1. ✍️ Algorithm Description

    • Explain what the algorithm does
    • Describe the approach and methodology
    • Include use cases or applications
  2. 📊 Complexity Analysis

    • Time complexity (e.g., O(n log n))
    • Space complexity (e.g., O(n))
    • Brief explanation of why
  3. 💬 Meaningful Comments

    • Explain complex logic
    • Document function parameters
    • Add inline comments for clarity
  4. ✅ Test Cases/Examples

    • Demonstrate the code works
    • Show different input scenarios
    • Include edge cases

💡 Example Template

"""
Binary Search Algorithm

Description: Searches for a target value in a sorted array using divide-and-conquer

Time Complexity: O(log n) - halves search space each iteration
Space Complexity: O(1) - only uses constant extra space
"""

def binary_search(arr, target):
    # Initialize pointers
    left, right = 0, len(arr) - 1

    while left <= right:
        mid = (left + right) // 2

        # Check if target found
        if arr[mid] == target:
            return mid
        # Search right half
        elif arr[mid] < target:
            left = mid + 1
        # Search left half
        else:
            right = mid - 1

    return -1  # Not found

# Test cases
if __name__ == "__main__":
    test_arr = [1, 3, 5, 7, 9]
    print(binary_search(test_arr, 5))  # Output: 2
    print(binary_search(test_arr, 6))  # Output: -1
