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) → 0triangle(1) → 1triangle(2) → 3...Save, Compile, Runpublic int triangle(int rows) { } Show output only (no red/green) prev  |  next  |  chance   |  CodingBat  >  Recursion-1
