You can start from     any row in the left wall. 5. You are allowed to move 1 cell right-up (d1), 1 cell right (d2) or 1 cell right-down(d3). 6. Each cell has a value that is the amount of gold available in the cell. 7. You are required to identify the maximum amount of gold that can be dug out from the mine. Input Format A number n A number m e11 e12.. e21 e22.. .. n * m number of elements Output Format An integer representing Maximum gold available. Constraints 1 <= n <= 10^2 1 <= m <= 10^2 0 <= e1, e2, .. n * m elements <= 1000 Sample Input 6 6 0 1 4 2 8 2 4 3 6 5 0 4 1 2 4 1 4 6 2 0 7 3 2 2 3 1 5 9 2 4 2 7 0 8 5 1 Sample Output 33 --- Send in a voice message: https://podcasters.spotify.com/pod/show/rahulsain/message
