Elements of a list are numbered starting at 0. This matches with the Range (`↕`) function we saw earlier, in that the value of Range's result at a particular index is equal to that index. As an illustration, we can pair up each element of a list with its index by calling Range on the list's length. - (↕3) ≍¨ "BQN" + (↕3) ⋈¨ "BQN" 1 ⊑ "BQN" |
