Problem:
Consider the following method.
public static helper(int m, int n)
{
while (m > n)
{
m -= n;
}
return m;
}
}
Which of the following operations does the method helper implement?
- calculating a power,
mn - integer division,
m / n - integer division,
m % n - integer multiplication,
m * n
The correct answer is c. The dividend, represented by m, has the divisor n subtracted from it until m is less than n, at which point no additional subtractions can be performed without producing a negative result. The remaining value of m is... the "remainder," the result produced by the modulo, or mod or % operation in integer division.
