Find-Pi-by-random - Find Pi by random shots
main [options]
The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159.
This program makes the "shots" in the square and finds hits in relation to all the inscribed circle "shots".
This program was test from interview to Прогрэдис, Russian IT company. One my friend sends this to me: You have foursquare and inscribed circle, you have to do random shots to the foursquare and find Pi.
