We’re not going to sugarcoat it: Chicago’s winters can be
rough. The temperatures sometimes dip to uncomfortable levels
and, after last year’s “polar vortex”, the University of
Chicago Weather Service wants to find out exactly how bad the
winter was. More specifically, they are interested in knowing
the total number of days in which the temperature was below
zero degrees Celsius.
Input
The input is composed of two lines. The first line contains
a single positive integer $n$ ($1
\le n \le 100$) that specifies the number of
temperatures collected by the University of Chicago Weather
Service. The second line contains $n$ temperatures, each separated by a
single space. Each temperature is represented by an integer
$t$ ($1\, 000\, 000 \le t \le 1\, 000\,
000$)
Output
You must print a single integer: the number of temperatures
strictly less than zero.
