Premium Minds Test

Pokemon Test from Premium Minds Company

Test Description

Pokemon: Catch them all

Ash is catching Pokemon in a world consisting of an infinite two-dimensional grid of houses. In each house there is exactly one pokemon.

Ash starts by catching the pokemon that is in the house where he starts. Then, move to the house immediately north, south, east or west of where you are and catch the pokemon that is there, and so on. Attention: if he passes a house where he has already passed (and therefore where he has already caught a pokemon), there is no longer a pokemon for him to catch!

What we want to know is: starting with a world full of pokemon's (one in each house!), how many pokemon's does Ash catch for a given sequence of moves?

Input Format

The program must read a line from stdin, which contains a sequence of movements. Each movement is described by a letter N, S, E or O (respectively: north, south, east, west in portuguese).
