Probably because you have an error in you program.

void dfs(int i,int j,int k){
    if(i==-1 && j==-1) return ;

Should it be if (i <= 0 || j <= 0)?

p.s. about the difference of the correct answer and your output: try to run your code on your own machine and see what your program will produce as output.
