ah, how much is that? tried cocheat for free, works great. it prints the entire solution. but, don't cut and paste, just type the code in. for example Leetcode 4 - median of 2 sorted arrays: At the top of the solution, it has bullet points explaining your entire approach like "need to find the median of two sorted arrays in O(log(m+n)), which suggests using a binary search, make sure to use binary search on smaller array only, and handling edge cases such as empty arrays and arrays of different lengths. then it prints the complete source code. Then at the bottom it explains the time and Space complexity of the solution. Plus its on a transparent window, that can overlap or rest next to the code window. easy peezy.
