  • Rootish Array Stack (correct)
  • Array
  • Array Stack
  • LinkedList

What is the formula to calculate the number of elements stored in the Rootish Array Stack?

  • $r^2 + r = 2n$ (correct)
  • $b = (-3 + \sqrt{9 + 8i})/2$
  • $j = i - b(b + 1) / 2$
  • $r + 1 = $block size

What is the equation to find the index $i$ given the block number $b$?

  • $i = j - b(b + 1) / 2$
  • $i = j + b(b + 1) / 2$ (correct)
  • $j = i - b(b + 1) / 2$
  • $j = i - b$
