Hi,

I am working on below challenge

http://codingbat.com/prob/p194781
Recursion-1 > triangle

prev | next | chance

We have triangle made of blocks. The topmost row has 1 block, the next row down has 2 blocks, the next row has 3 blocks, and so on. Compute recursively (no loops or multiplication) the total number of blocks in such a triangle with the given number of rows.

triangle(0) → 0

triangle(1) → 1

triangle(2) → 3

i have not understood above description.

what is row and what is block and how they are related to triange and what we have to return

Can you please advise
