Problem Statement

N of us are going on a trip, by train or taxi.

The train will cost each of us A yen (the currency of Japan).

The taxi will cost us a total of B yen.

How much is our minimum total travel expense?

Constraints

All values in input are integers.

1 \leq N \leq 20

1 \leq A \leq 50

1 \leq B \leq 50

Input

Input is given from Standard Input in the following format:

N A B

Output

Print an integer representing the minimum total travel expense.

Sample Input 1

4 2 9

Sample Output 1

8

The train will cost us 4 \times 2 = 8 yen, and the taxi will cost us 9 yen, so the minimum total travel expense is 8 yen.

Sample Input 2

4 2 7

Sample Output 2

7

Sample Input 3

4 2 8

Sample Output 3

8

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)

"use strict"

var inputs = '';
var reader = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
})

reader.on('line', function(input) {
  inputs = input
})

reader.on('close', function() {
  let items = inputs.trim().split(' ')
  let n = parseInt(items[0])
  let a = parseInt(items[1])
  let b = parseInt(items[2])
  let train = n * a
  let taxi = b
  if(train < taxi){
    console.log(train)
  }else
    console.log(taxi)
})
