Given an integer array nums and an integer k, return the maximum length of a subarray that sums to k. If there is not one, return 0 instead. Solution 注意到是 subarray, 所以是连续的。因此我们用 \(map\) 来记录一下当前 \(cursum\) 第一次出现下标位置，所以如果此时

ProgressBar ProgressBar和Slider相比，无法响应鼠标和键盘，只是显示任务的进度。 它有2种用法： （1）Minimum，Maximum，Value显示任务的实时精确进度。 （2）IsIndeterminate设置成true，会忽略Minimum，Maximum，Value，一直有个脉冲在滚动。任务完成后，可以设置成false，并把Value等于Maximum。

You are given an integer array nums of length n and an integer numSlots such that 2 * numSlots >= n. There are numSlots slots numbered from 1 to numSlots. You have to place all n integers into the slots such that each slot contains at most two numbers.

You have a tortilla with radius 1 and wish to form a cone. You may cut out any wedge you like from the tortilla. The point of the wedge must be at the center of the circle. After cutting out the wedge you then attach the two straight edges remaining to fo

You are given an m x n integer matrix points (0-indexed). Starting with 0 points, you want to maximize the number of points you can get from the matrix. To gain points, you must pick one cell in each row. Picking the cell at coordinates (r, c) will add po
