Solution

For this, consider that since each strip (with the exception of the first one) will be plugged into another strip, if we have a total of X outlets across K strips, then we have X-(K-1) outlets available for appliances. So, read each line and total them all up, and subtract K-1, or start a tally to -(K-1) and add every O value read.
