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, 3, 4, 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~.
Comments
Cool question
man I feel like cheesing this question by printing on the second line
