<ul><li>The sliding window approach is perfect for problems involving subarrays or subsequences where we need to find a continuous segment that satisfies certain conditions.</li><li>The core idea is to expand our window by moving the right pointer forward until our window no longer satisfies our condition. Then we shrink it from the left until the condition is satisfied again.</li><li>The sliding window technique excels in problems where you need to find optimal subarrays or need to maintain a running calculation over a window of elements.</li><li>The sliding window technique is versatile and can be applied to many problems involving contiguous subarrays or substrings.</li></ul>
