Find the Minimum in a List

A weather station writes each week's daily low temperatures onto a single line, in degrees Celsius. The monthly report opens with the coldest reading of the week, and in winter every reading on the line can be below zero.

Task: Read one week of readings and print the coldest one.

Input

A single line holding between 1 and 100 integers, separated by single spaces. Any of them may be negative or zero.

Output

One line holding a single integer: the smallest value on the line.

Example:

Input:
5 2 8 1 9
