## We want to run LSTM on a batch of 3 character sequences ['long_str', 'tiny', 'medium']
#
#     Step 1: Construct Vocabulary
#     Step 2: Load indexed data (list of instances, where each instance is list of character indices)

[[0, 1], [2, 3], [4, 5]].reduce((prev, item) => item.map((_, i) => [...(prev[i] || []), item[i]]), []); // [[0, 2, 4], [1, 3, 5]]
