The International Mathematical Olympiad (IMO) is the World Championship Mathematics Competition for High School students and is held annually in a different country. The first IMO was held in 1959 in Romania, with 7 countries participating. It has gradually expanded to over 90 countries from 5 continents. The IMO Advisory Board ensures that the competition takes place each year and that each host country observes the regulations and traditions of the IMO

Original Problem: 1000 slaves in a circle, numbered 1 to 1000, are
all to be shot except one lucky survivor. The order of shooting is
1, 3, 5, etc., always alternating, and always immediately removing
the fallen bodies. Once a body has fallen, it is no longer
considered part of the circle for purposes of future counting and
alternation. Example, n=6: Shoot 1,3,5,2,6; 4 survives.
