SUMITR - Sums in a Triangle

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 100;
  • all numbers are positive integers between O and 99.

Take care about your fingers, do not use more than 256 bytes of code.


In the first line integer n - the number of test cases (equal to about 1000). 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.


2 1
1 2 3
1 2 
4 1 2
2 3 1 1

Wow! the space thing is tougher than problem,

what is the point of such source code limit? as a challenge problem it would be fine, here only made me frustrated (as I wanted to write in java). Btw, anyone with < 320 LOC in java?

i think setter has space problem...

What's the point of 256 B?
just to writer everything in one line?

Finally AC!!! phewwww

Code size restriction of 256B is really wrong.

AC in 1st go :) A little bit of code golf in Python after a very long time.. was fun :D
