  ['10','11','12','13']
  ['20','21','22','23']
  ['30','31','32','33']

# Size
size = map.length

# Top half of array
for i in [0...size]
  for j in [0...(i + 1)]
    console.log "#{j}, #{i-j}"

# Bottom half of array
for i in [1...(size + 1)]
  for j in [0...(size - i)]
    console.log "#{i+j}, #{map.length-j-1}"
