Thursday Online Python Homework 08.22

28 Aug Thursday Online Python Homework 08.22

Question:

please read question and try to understand it. Then the sample of input, output and explaination of output will help you a lot.

Problem Description:
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 1000, each representing the distances between consecutive pairs of consecutive cities: specifically, the ith integer represents the distance between city i and city i + 1.

Output Specification
The output should be 5 lines, with the ith line (1 ≤ i ≤ 5) containing the distance from city i to cities 1, 2, … 5 in order, separated by one space.


Sample Input
3 10 12 5

Output for Sample Input
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 of Output for Sample Input
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.
