The Sliding Problem contains a sliding window which is a sub – list that runs over a Large Array which is an underlying collection of elements. 滑动窗口算法可以用以解决数组/字符串的子元素问题,它可以将嵌套的循环问题,转换为单循环问题,降低时间复杂度。 假设有数组[a b c d e f g h]一个大...
Sliding window algorithm is used to perform required operation on specific window size of given large buffer or array. 滑动窗口算法是在给定特定窗口大小的数组或字符串上执行要求的操作。 This technique shows how a nested for loop in few problems can be converted to single for loop and hence reduci...
In the sliding window technique, we maintain a window that satisfies the problem constraints. The window is unstable if it violates the problem constraints, and it tries to stabilize by increasing or decreasing its size. Following are some of the commonly asked interview questions that use the sl...
结果非常理想,竟然击败了100%的人,用时36ms,不得不说Sliding Window algorithm用O(n)的时间复杂度就可以解决substring searching的问题,非常非常有效。强烈建议理解这种方法。 Minimum Window Substring Given a string S and a string T, find the minimum window in S which will contain all the characters in...

Computation on sliding window This approach to computation is known as computation in the sliding window. A sliding window is just a dataset part selection algorithm but exact aggregating computation algorithms can vary. We need to consider a specific aggregation algorithm known as median computation....

sliding-window algorithmwireless cognitive networkTo improve the performance of spectrum sensing, cooperation among Cognitive Radios (CRs) has been proposed recently as an effective solution. Most existing works require either time synchronization or extra infrastructure support, which are not ...
