The following program segment swaps the first element and the second element of the given array without using the third variable, fill in the blanks with…

void swap()
{ int x[] = {4, 8, 19, 24, 15};
x[0] = x[0] * x[1];
x[1] = x[0] / x[1];
x[0] = x[0] / x[1];
System.out.println(x[0] + " " + x[1]); }

Explanation

The first two elements of the array are:

• x[0] = 4
• x[1] = 8

The swapping is done without using a third variable by using multiplication and division.

Step 1

x[0] = x[0] * x[1];

So,

x[0] = 4 * 8 = 32

Now:

• x[0] = 32
• x[1] = 8

Step 2

x[1] = x[0] / x[1];

So,

x[1] = 32 / 8 = 4

Now:

• x[0] = 32
• x[1] = 4

Step 3

x[0] = x[0] / x[1];

So,

x[0] = 32 / 4 = 8

Now:

• x[0] = 8
• x[1] = 4

Thus, the values of the first and second elements are interchanged.

Output

8 4
