    If they allowed to use an ArrayList as the return type then we would not need the newDigits array then.

    public int[] plusOne(int[] digits)
    {
    int val=0,flag=0,i;
    for(i=digits.length-1;i>=0;i--)
    {
    val=digits[i]+1;
    digits[i]=val%10;
    if(val>=10)
    continue;
    else
    {
    break;
    }
    }
    if(i<0)
    {
    int[] newDigits=new int[digits.length+1];
    newDigits[0]=1;
    return newDigits;
    }
    return digits;

     }
