My code is running fine but test case going false
public static void main(String[] args) {
System.out.print("");
Scanner sc=new Scanner(System.in);
int rows=sc.nextInt();
int columns=sc.nextInt();
//System.out.println(""); dont need this
int [][] arr=new int[rows][columns];
for(int i=0; i<columns;i++)
{
for(int j=0; j<rows;j++)
{
arr[j][i]=sc.nextInt();
}
}
printColWise(arr);
}
public static void printColWise(int[][] arr) {
for(int i=0;i<arr.length;i++) {
if(i%2==0) {
for(int j=0;j<arr[i].length;j++) {
System.out.print(arr[i][j]+", “);/////////add space after each number
}
}else {
for(int j=arr[i].length-1;j>=0;j–) {
System.out.print(arr[i] [j]+”, ");/////////add space after each number
}
}
}
System.out.print(“END”);
}
}
