Scientists are involved in a study to record the total number of bad winter days in a month. They have obtained the file which consists of the temperature data of a certain month. Write a program in C++ that will read this file and be able to count the total number of days in that given month for which temperature was below zero degree Celsius. You can assume that the maximum number of weeks that can be recorded for a month is at most four and the maximum number of days is at most twenty eight.

The input file structure is as follows:

line 1: an integer value depicting the total number of weeks

line 2: an integer value depicting the number of days for each week that was recorded

line 3 and onwards: integer values (positive and negative) depicting the recorded temperature in degree Celsius for that day

Example Input File:

1 //recorded only for 1 week

3 // recorded only the first 3 days of each week

5 -6 8 //temperature reading for the first 3 days

Your program output for the above example input file should return the value 1 (total number of temperature readings below zero degree Celsius).
