Maximum of three

Challenge

Return the largest of three integers.

Task

Implement int max3(int a, int b, int c) that returns the largest of the three values. No main — the grader calls it.

Input

Three ints a, b, and c.

Output

Returns the maximum of the three, as an int.

Example

max3(3, 1, 2)      ->   3
max3(1, 5, 2)      ->   5
max3(1, 2, 9)      ->   9
max3(-3, -1, -2)   ->   -1

Edge cases

• All-negative inputs return the largest (closest to zero).

Input format

Three ints a, b, and c.

Output format

The largest of the three, as an int.

Constraints

a, b, and c are signed 32-bit integers.

Starter code

int max3(int a, int b, int c) {
    /* TODO */
    return 0;
}

Common mistakes

Writing complex compound boolean expressions that miss duplicate maximum values.

Edge cases to handle

All identical values, two identical values, all negative values.
