So I was solving this problem on LeetCode. This is my AC code in Java. After this I tried solving a similar problem on the CodeStudio platform which was this. As you can see, this problem is very much similar to the LC problem with the only difference being the direction in which we can move and the fact that the ending index , instead of being the bottom right cell, can be any cell in the bottom row. So, in the LC problem my code was getting terminated whenever the current x & y coordinates of the cell became equal to the coordinates of the bottom right cell.

Now to solve the CodeStudio problem, what I tried doing was, since the end index can be any cell in the last row , I ran a loop from i = 0 to i = n-1 and kept finding out the min value possible from [0][0] to [n-1][i]. I check for every cell in the last row and return the minimum value whatever it may be as you can see in this code. (ignore the compilation errors since I am not writing the Main class.) However this code gave correct output for only 9/11 test cases and gives wrong answer for the other two. So it would be of great help to me if anybody can point out the error in my logic as to why those 2 TCs fail . Thank you
