这题不太好想.可以先扫描找到最高的柱子,然后分别处理两边:记录下当前的局部最高点,如果当前点小于局部最高点,加上, 反则,替换当前点为局部最高点. int trapWater(int A[], int n) { ; ; ; ; i < n; i++) { if (A[i]>A[max])max = i; } ; i < max; i++) { if (A[i]>peak) peak = A[i]; else water += peak - A[i]; } ; j > max;…

Given an m x n matrix of positive integers representing the height of each unit cell in a 2D elevation map, compute the volume of water it is able to trap after raining. Note: Both m and n are less than 110. The height of each unit cell is greater th…

Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. For example, Given [0,1,0,2,1,0,1,3,2,1,2,1], return 6. The above elevation map is represented by a…
