Canadian Computing Competition: 2018 Stage 1, Junior #3

You decide to go for a very long drive on a very straight road. Along this road are five cities. As you travel, you record the distance between each pair of consecutive cities.

You would like to calculate a distance table that indicates the distance between any two of the cities you have encountered.

Input Specification

The first line contains ~4~ positive integers less than ~1\,000~, each representing the distances between consecutive pairs of consecutive cities: specifically, the ~i~th integer represents the distance between city ~i~ and city ~i + 1~.

Output Specification

The output should be ~5~ lines, with the ~i~th line ~(1 \le i \le 5)~ containing the distance from city ~i~ to cities ~1, 2, \ldots 5~ in order, separated by one space.

Sample Input

3 10 12 5

Sample Output

0 3 13 25 30
3 0 10 22 27
13 10 0 12 17
25 22 12 0 5
30 27 17 5 0

Explanation for Sample Output

The first line of output contains:

• ~0~, since the distance from city ~1~ to city ~1~ is ~0~;
• ~3~, since the distance between city ~1~ and city ~2~ is ~3~;
• ~13~, since the distance between city ~1~ and city ~3~ is ~3 + 10 = 13~;
• ~25~, since the distance between city ~1~ and city ~4~ is ~3 + 10 + 12 = 25~;
• ~30~, since the distance between city ~1~ and city ~5~ is ~3 + 10 + 12 + 5 = 30~.
