With this information we can use binary search where initially low = 1 and high = maximum element + 1 and find the number of tours required when number of items needed to be delivered per tour is mid where mid = low + (high . If someone has the heart to study all the leetcode they deserve to get phone screened and chance for onsite. Continuing this pattern for one more round we calculate an area of 49 for the new position i, j , update our largest area observed, and notice that height[i] > height[j] so we decrement j. At each stage, assign the next value to the container which is currently smallest. Example 1: Input: height = [1,8,6,2,5,4,8,3,7] Output: 49 Explanation: The above vertical lines are represented by array [1,8,6,2,5 .
