You are given an integer array height of length n. There are n vertical lines drawn such that the two endpoints of the ith line are (i, 0) and (i, height[i]).Find two lines that together with the x-axis form a container, such that the container contains the most water.Return the maximum amount of water a container can store.Notice that you may not slant the container.
You are given an integer array target. You have an integer array initial of the same size as target with all elements initially zeros. In one operation you can choose any subarray from initial and increment each value by one. Return the minimum number of operations to form a target array from initial. The test cases are generated so that the answer fits in a 32-bit integer.
You are given an integer array nums and an integer k.You are allowed to perform the following operation on each element of the array at most once:Add an integer in the range [-k, k] to the element.Return the maximum possible number of distinct elements in nums after performing the operations.
