Space Mission

We are sending a probe to Mercury to record temperature, which varies from -100 to +150 degrees.

the probe takes 200 readings over the course a day, evenly spaced, and it recorded all of them in its memory.

The recorded data is sent back to earth once a day. Due to bandwidth limitations, only 100 bytes can be sent per day.

Scientists looking at this data will want to know the temperature at any time of the day, accurately.

in what format will you send the data? Give an Algorithm and explain why?
