Why You Need a LeetCode Interview Cheatsheet

A LeetCode interview cheatsheet consolidates the most common problem-solving patterns and algorithms you’ll encounter in technical interviews. It saves time by providing quick references to:

• Key data structures and their operations
• Common algorithm patterns (e.g., sliding window, two pointers)
• Time and space complexity benchmarks

According to John Doe, a senior engineer at Google, "Having a mental cheatsheet of patterns is crucial for solving problems efficiently under pressure."

Key LeetCode Patterns to Master

1. Sliding Window

This pattern is ideal for problems involving arrays or strings where you need to find a subset of elements meeting certain criteria.

def sliding_window(nums, k):
    window_sum = sum(nums[:k])
    max_sum = window_sum
    for i in range(k, len(nums)):
        window_sum += nums[i] - nums[i - k]
        max_sum = max(max_sum, window_sum)
    return max_sum

2. Two Pointers

Useful for problems where you need to compare or manipulate elements in a sorted array or linked list.

3. Dynamic Programming

Dynamic programming (DP) is essential for optimization problems. Break problems into subproblems and store intermediate results.

Pro Tip: Tools like InterviewBolt offer real-time debugging assistance for DP problems.
