WitrynaIMO Shortlist 1999 Combinatorics 1 Let n ≥ 1 be an integer. A path from (0,0) to (n,n) in the xy plane is a chain of consecutive unit moves either to the right (move denoted by E) or upwards (move denoted by N), all the moves being made inside the half-plane x ≥ y. A step in a path is the occurence of two consecutive moves of the form EN.
