Merge Two Sorted Strings Lexicographically

Understand how to recursively merge two sorted strings in lexicographical order, comparing characters and handling base cases. This lesson teaches you recursive string manipulation to maintain sorted order in the merged output.

What does “Merging Two Sorted Strings Lexicographically” Mean?

Lexicographical means that something is organized according to alphabetical order.

Lower case letters are different from upper case letters and are therefore treated as different elements. All upper case letters come before lower case letters. Alphabetic sorting is as follows: $A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z, a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z$

In this task, we’re merging two strings (that are themselves sorted). Have a look at the illustration below: ...
