1 设置targetmap和windowmap用来记录字符出现的次数以及窗口中字符出现的次数 2 设置start变量,end变量,minstart,minlength 3 设置valid变量以及targetnum为Object.keys(targetmap)的值 4 更新start和end,去更新targetmap和windowmap的值 5 如果valid === targetmap,去更新start向右,记住这个过程中要去更新windowmap和vali...

I'm trying to apply a sliding window minimum and maximum filter to an image of a certain window size. Actually, I'm trying to find the optimum window size for it. But I really haven't gotten the hang of it. I presume that I should be using blockproc to implement the sliding window,...

链接:http://leetcode.com/problems/minimum-size-subarray-sum/ 题解: 首先想到滑动窗口sliding window,从0开始累加,当和Sum大于等于S的时候再从左侧减小窗口,继续进行判断。 Time Complexity - O(n),Space Complexity - O(1) publicclassSolution {publicintminSubArrayLen(ints,int[] nums) {//sliding windo...
Approach #2 Sliding Window 我想了类似的题目比如subarray sum equals k,523. Continuous Subarray Sum等等,都是用一个map储存过往的值,然后要么减去k,要么mod k;所以这题我也想map,结果发现这个是要求>=一个值而不是一个精确值,有可能map不到啊。跟567. Permutation in String类似用Sliding window,两个指针。
Several window functions are currently applied to improve the performance of the discrete Fourier transform (DFT) harmonic detection method. These window functions exhibit poor accuracy in measuring the harmonic contents of a signal with high-order and weak-amplitude components when the power frequency ...
还是sliding window的思路做。给两个指针left和right,也用一个变量sum记录遍历到的数字们的加和。遍历的时候一开始也是只移动右指针,当sum >= S的时候,开始试图移动左指针。所谓的最短的子数组也就是左右指针的距离最短,所以每次当sum >= S的时候,需要记录right - left的值。注意有可能最后是找不到一个子数...

On Sept. 14, 1999, Category 2 Hurricane Floyd struck the East Coast, hittingNorth Carolina first and the hardest. Twelve other states were affected and 10 were declared major disaster areas. The large size and range of Floyd resulted in heavier and longer-lasting rains--10 to 20 inches over...
