AoC Day 3

'''
SIDE = 1000
FORMAT: (ID @ LEFT,RIGHT: XxY)
Part 1
How many square inches of fabric are within two or more claims?
Solution:
Create 1000 arrays with 1000 indices
Loop through each entry of the input.txt to record the positions.
For each use, add 1 to the array indice.
e.g. 5,5 5,5 the spaces filled would be 6=left+1 to 11=left +5, 6=top+1 to 11=top+5
in the actual array: the first would be array[6][6] to array[11][11]
@ space1 number comma number colon space2 number x number
