 #!/usr/bin/env node // Solve the "Coin Change" problem using a bottom-up dynamic programming // approach. The time complexity is O(n * coins.length) since we have a nested // loop. The storage complexity is the same, as we store a matrix. // // * `coins` is an array of the coin values, eg. [ 1, 2, 3 ]. We assume it // to be non-empty. // * `n` is the amount, eg. 4 cents. //
