Temperature Checkpoint Differences

You are given the temperatures at m checkpoints before and after a heatwave. The original temperatures are provided for context, but your task is to compute the differences between consecutive checkpoints from the new temperatures. For each consecutive pair, compute the difference as:

$$d_i = new\_temps_{i+1} - new\_temps_{i}$$

If there is only one checkpoint (m = 1), then no difference can be calculated, and the output should be empty.

inputFormat

The input is given via stdin and has the following format:

m
original_temp_1 original_temp_2 ... original_temp_m
new_temp_1 new_temp_2 ... new_temp_m

Here, m is an integer representing the number of checkpoints. The second line contains m integers representing the original temperatures, and the third line contains m integers giving the new temperatures recorded after the heatwave.

outputFormat

Output via stdout a single line consisting of m-1 integers. Each integer is the difference between two consecutive new temperatures. The differences should be separated by a single space. If there are no differences (i.e. when m = 1), output an empty line.
