Problem 2147. Langston's Ant
The Langston's Ant Challenge is to determine the number of Black squares after K Ant moves.
An infinite white board has an Ant at the center. Direction is not required.
Movement and Affect:
1) At a white square, turn 90° right, White goes to Black, move forward one unit 2) At a black square, turn 90° left, Black goes to White, move forward one unit
After a given number of moves how many Black squares are present.
Input: K, number of moves from 100 to 12000
Output: BLK, number of Black squares
Example: K=5, BLK=3 [00000;00010;00110]
Note: After 11000 moves a pattern emerges
