# test case wrong?

• I run the same testcase in my IDE, the result is 1. Why here is 2.

Input:
["W","E","W","0","E"]
Output:
2
Expected:
1

public int maxKilledEnemies(char[][] grid) {

int m = grid.length;
if(m == 0) return 0;
int n = grid[0].length;
int rowKill=0, res = 0;
int[] colKill = new int[n];
for(int i=0;i<m;i++){

for(int j=0;j<n;j++){
if(j==0 || grid[i][j-1] == 'W'){
rowKill = 0;
for(int k=j;k<n && grid[i][k]!='W';k++){
rowKill += grid[i][k] == 'E'?1:0;
}
}
if(i==0 || grid[i-1][j] == 'W'){
for(int k=i;k<m && grid[k][j]!='W';k++){
colKill[j] += grid[k][j] == 'E'?1:0;
}
}
if(grid[i][j] == '0'){
res = Math.max(res, rowKill + colKill[j]);
}
}
}

return res;
}

• @hot13399 said in test case wrong?:

I run the same testcase in my IDE, the result is 1.

Then you didn't really use that code and that test case. If you did, the result would be 2 in your IDE as well.

• Thank you @StefanPochmann , yes, I misunderstood the testcase, and there is a bug in my code.
["W","E","W","0","E"] actually means:

char[][] grid= new char[][]{{'W'},{'E'},{'W'},{'0'},{'E'}};
