Hello Everyone, I was solving this problem: 722E][PROBLEM: - Research Rover. I was able to solve this by counting the number of paths that pass through the 0, 1, 2 and so on anomalies along with the sum of anomalies of each path. But I am wondering whether this problem can be solved using the lemma of linearity of expectation (LOE). LOE is quite trivial on 3000 * 3000 grid. But how to do LOE when size of grid is 1<=n,m<=1e5.
Thanks in advance!
