TRI_SUMS - Sums in a triangle (challenge)

Let us consider a triangle of numbers in which a number appears in the first line, two numbers appear in the second line etc. Develop a program which will compute the largest of the sums of numbers that appear on the paths starting from the top towards the base, so that:

  • on each path the next number is located on the row below, more precisely either directly below or below and one place to the right;
  • the number of rows is strictly positive, but less than 101;
  • all numbers are positive integers between 0 and 1002.


In the first line integer n - the number of test cases (less than 101). Then n test cases follow. Each test case starts with the number of lines which is followed by their content.


For each test case write the determined value in a separate line.

@Abhishek Gupta - Yes, for every task in this contest score is source length.

@author: does the result implies bytes of code?

The judge seems to be broken: There is a 0 byte solution. Same for problem BINOMIAL.

[kuszi: Thank you for pointing this out, fixed]

You're right. I forgot to change input specification a bit. Thank You. :-)

There seems something wrong with the input. My AC solution for SUMTRIAN/SUMITR gives NZEC here.
Edit 1: Pascal works, Python doesn't.
Edit 2: Problem identified and solved. Could be bad line ends or values > 99.
