Using C++ Only Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it can trap after raining. Example 1: Input: height =...

Note:Use the input as the variable height and provide as default in the code. Do not write code such that it asks user to enter input,  the code must run and only print the output given.
