Understanding and applying patterns helps in writing optimized code and improves the efficiency of solutions.
These are some leetcode patterns you should definitely checkout:
1️⃣ Arrays: Data structures, such as arrays, store elements in contiguous memory locations. They are versatile and useful for a wide variety of purposes.
LeetCode Problems:
- Search in Rotated Sorted Array (Problem #33)
- Product of Array Except Self (Problem #238)
- Find the Missing Number (Problem #268)
2️⃣Two Pointers: In Two Pointers, two pointers are maintained in the collection and can be manipulated to solve a problem efficiently.
LeetCode problems:
- Trapping Rain Water (Problem #42)
- Longest Substring Without Repeating Characters (Problem #3)
- Squares of a Sorted Array (Problem #977)
3️⃣In-place Linked List Traversal: As an explanation, in-place traversal is a technique for modifying linked list nodes without using extra space.
LeetCode Problems:
- Remove Nth Node From End of List (Problem #19)
- Palindrome Linked List (Problem #234)
- Reorder List (Problem #143)
4️⃣Fast & Slow Pointers: This pattern uses two pointers to traverse a sequence at different speeds (fast and slow), often used to detect cycles or find a specific position in the sequence.
LeetCode Problems:
- Happy Number (Problem #202)
- Subarray Sum Equals K (Problem #560)
- Intersection of Two Linked Lists (Problem #160)
5️⃣Merge Intervals: This pattern involves merging overlapping intervals in a collection, often used in problems dealing with intervals or ranges.
LeetCode problems:
- Non-overlapping Intervals (Problem #435)
- Minimum Number of Arrows to Burst Balloons (Problem #452)
- Employee Free Time (Problem #759)
