What are some common algorithm design patterns used in coding interviews?
Common algorithm design patterns include sliding window, two pointers, fast and slow pointers, and divide and conquer.
Can you explain the sliding window pattern with an example?
Sure! The sliding window pattern is used to solve problems involving subarrays or substrings. For example, finding the maximum sum of a subarray of size k.
What about the two pointers pattern?
The two pointers pattern involves using two pointers to traverse a data structure. A classic example is finding pairs in a sorted array that sum to a target value.
How can I prepare for questions on these patterns in interviews?
Practice coding problems that specifically require these patterns, and review common interview questions that utilize them.
