For the following method and method calls, write what will be printed to the console when the method call is executed.

Solution

//This will print the values starting from i, till j, in a way such that, the increment
//value increases linearly from 1, and will continue, till the value reaches j.
//So, the series will be, i, i+1, i+1+2, i+1+2+3, i+1+2+3+4,.....
public static void whileMystery(int i, int j)
{
int k = 0;       //Defines a variable k and will assign to 0.
while(i < j && k < j)   //This loop runs till both i and k values are both less than j.
{
i = i + k;           //i increased by a step of k.
j--;                   //j is reduced by 1.
k++;                   //k is increased by 1.
System.out.print(i + \", \");   //Prints i value.
}
System.out.println(k);    //Prints k value.
}

For example if the function is called with parameters whileMystery(2, 10), the output is: 2, 3, 5, 8. And the final k will print the number of values printed, i.e., 4 in this case.
