The Gold Mine Problem. Greedy or Dynamic? by Sakshi

2020-10-13  According to the rules of the gold mining problem, the miner can be at any row but should be at the first column. So, now that we are testing the greedy approach, we should select the maximum element in the 1st column, which is 3 located at (2,0). After we take 3, we can either take 6 (diagonally above to the right) or 0 (to the right).
