1. 1st thing I come up with is to use binary search, but it has LTE problem (1) maintain the index of each interval by create a tuple (2) sort the list by the start point (3) iterate each interval, find the end point endElement (4) binary search the right most insertion position...

11. Pattern: Modified Binary Search,改造过的二分 当你需要解决的问题的输入是排好序的数组,链表,或是排好序的矩阵,要求咱们寻找某些特定元素。这个时候的不二选择就是二分搜索。这种模式是一种超级牛的用二分来解决问题的方式。 对于一组满足上升排列的数集来说,这种模式的步骤是这样的: 首先,算出左右端点的...

In this question, we represent the board using a 2D array. In principle, the board is infinite, which would cause problems when the active area encroaches the border of the array. How would you address these problems? 【解答】状态转换的问题,把代码逻辑想清楚再写。这类题算法本身不难,也没什...
