STRANAXFRM(3) C Programmer's Manual STRANAXFRM(3) NAME stranaxfrm - make a string into canonical form for anagram comparison SYNOPSIS #include <publib.h> char *stranaxfrm(char *str); DESCRIPTION stranaxfrm transforms a string into a canonical form for anagram com- parisons. To check whether two strings are anagrams of each other (i.e., they contain the same characters, but in different order), com- pare their canonical forms. The canonical form merely has all the characters in the string sorted into ascending order. To write a program to find anagrams, first convert a word list into canonical order, then look up words in that version of the word list by transforming them also to canonical order. RETURN VALUE stranaxfrm returns its argument. BUGS This function is of a whimsical nature.
