Check if given array can be made 0 with given operations performed any number of times | Java implementation of the approach ; Function to whether the array can be made zero or not ; Count for even elements ; Count for odd elements ; Traverse the array to count the even and odd ; If arr [ i ] is odd ; If arr [ i ] is even ; Check if count of even is zero or count of odd is zero ; Driver 's Code
