This is my solution link for ANCOIMP

can anyone please tell me which test case is failing
my approach was :
Initalize zero=0;one=0 and the resultant array to -1;
1)start from 1st row and start searching i=1;j=1;
2)if value=1,search down that entire column
3)where ever on that column is 1,mark that row
suppose matrix is
010
101
010
so row 1 and row 3 will be marked
the resultant array[1]=array[3]=!array[2];
if array[2] is already initailzed then array[1]=array[3]=!array[2]
4)
but if not initialized then if zero<one
then array[2]=1;
and initialize other values according
