Challenge: Clamp with Macros

Lab C Intermediate 20 points

Write two macros, MIN(a, b) and MAX(a, b). Read three numbers x lo hi and print x "clamped" into the range lo..hi: if it is below lo print lo, if above hi print hi, otherwise x. Use MIN(MAX(x, lo), hi).

Input

Three integers x, lo, hi (lo ≤ hi).

Output

The clamped value.

Example

Input

Hints

Put brackets around every parameter in the macro.

Storing MAX(x, lo) in a variable first keeps the code simple.

Solution explanation

First we raise x to at least lo, then lower it to at most hi.

Show solution

#include <stdio.h>

#define MIN(a, b) ((a) < (b) ? (a) : (b))
#define MAX(a, b) ((a) > (b) ? (a) : (b))

int main() {
    int x, lo, hi;
    scanf("%d %d %d", &x, &lo, &hi);
    int raised = MAX(x, lo);
    printf("%d\n", MIN(raised, hi));
    return 0;
}
