Assignment In a data analysis application for environmental studies, temperature readings from a sensor are recorded in a sequence. Sudden temperature spikes or drops are significant and are marked when the difference between one reading and the next exceeds $5$ degrees.

Write code that reads a sequence of temperature readings $($as integers$)$ from standard input, terminated by a negative number. The code should identify and count occurrences where the absolute difference between consecutive readings exceeds $5$ degrees. After processing, print the count of such significant changes.

For example, given the sequence $"1215772216-1",$ the code should print $"2"$ because there are two instances where consequtive readings differ by more than $5$ degrees $(15$ to $7$ and $7$ to $22).$

Assume a scanner stdin object for standard input is provided.
