Before you do anything check for an empty List or a 0 divisor. if(divisor==0||array1.isEmpty()){ return false; } Then you can check the list. for(Integer i: array1){ if(i%divisor!=0){ return false; } } Finally. return true; solved logical OR in Java not working?
The meaning of Mod is that you take the remainder after doing the division. 1 fits zero times in 4, so the remainder is 1. Here the wikipedia definition that explains in a little more detail: In mathematics the result of the modulo operation is the remainder of an arithmetic division. As is well known, … Read more
Check Output you can understand every steps and what’s happening in every step using System; class MainClass { public static void Main (string[] args) { Console.WriteLine(“Please enter a number: “); int number = Convert.ToInt32(Console.ReadLine()); int sum = 0; while (number> 0) { Console.WriteLine(“Steps”); Console.WriteLine(“————–“); Console.WriteLine(“Digits: “+ (number % 10)); sum = sum + (number % … Read more
>>> l = [1,2,3,4,5,6] >>> N = len(l) >>> revL = l[::-1] >>> revL [6, 5, 4, 3, 2, 1] >>> for i in range(1,N): … print revL[-i:] + revL[:(N-i)] … [1, 6, 5, 4, 3, 2] [2, 1, 6, 5, 4, 3] [3, 2, 1, 6, 5, 4] [4, 3, 2, 1, 6, 5] … Read more
You can use modulus operation. $i = 1; foreach($records as $record){ echo $record; if ($i % 10 == 0) echo ‘<hr />’; $i++; } 1 solved How can I add a new row in a table every 10 columns automatically?

Note that if r is a primitive root modulo p. Then we can reduce complexity of the sum. We have to find S = a1*1 + a1*r + a1*r^2 + … + a1*r^n. Then we write S in the closed form as S = a1*(r^n – 1) / (r – 1). Now it can be … Read more
% is remainder operator. It gives the remainder after division. Quoting from MDN The remainder operator returns the remainder left over when one operand is divided by a second operand. It always takes the sign of the dividend, not the divisor. It uses a built-in modulo function to produce the result, which is the integer … Read more
