✨ STRANAXFRM ✨ (that's stranaxfrm from section 3pub of the C Programmer's Manual, bestie 💖)

🌸 NAME 🌸

stranaxfrm — the glow-up function that turns a string into its canonical form so you can do anagram comparisons 👑🦋

💅 SYNOPSIS 💅

#include <publib.h>
char *stranaxfrm(char *str);

🎀 DESCRIPTION 🎀

okay so. stranaxfrm takes a string and transforms it into a canonical form for anagram comparisons. that's the whole vibe. ✨

want to know if two strings are anagrams of each other? (iykyk: same characters, just shuffled around, different order, chaos.) then you literally just compare their canonical forms. that's it. that's the trick. 💖

and what is the canonical form, you ask? it's the string with all its characters sorted into ascending order. periodt. 🎀

so say you want to write a program that finds anagrams. here's the main character plan:

  1. convert a word list into canonical order first 🌈
  2. then look up words in that version of the word list, by transforming each word you're checking into canonical order too

boom. matching canonical forms = anagrams. slay. 🔥

💜 RETURN VALUE 💜

stranaxfrm returns its argument. yes, the same pointer you handed it. it just hands it right back. 🫶

💀 BUGS 💀

This function is of a whimsical nature. 🙈

that's it. that's the bug report. it's silly on purpose, bestie. no cap.
