Write a C++ program that will read a .txt file and will find the highest and lowest voltage, along with the associated time and ampere. The text file is large 1,000,000 rows of data, so speed is a factor. Per some of my own research it may be best to use mmap

Example of some of the data in the txt file

Time Volt Ampere

0.0001 9.77667 0.147408

0.00015 9.76583 0.147525

0.0002 9.76833 0.147692

0.00025 9.75833 0.147442

0.0003 9.76833 0.147192

0.00035 9.78167 0.1473
