char_merge

Transforming text24

Objective

Write a program that receives two strings and prints every unique character that appears in either one, without any duplicates. Output order is driven by the second string first, then any remaining characters from the first string.

Steps

The program expects exactly two arguments.
If the number of arguments is not 2, print wrong number of arguments followed by a newline.
Traverse the second string and print each character the first time it is seen.
Then traverse the first string and print each character that has not already been printed.
Each character must appear at most once in the output.
End the output with a newline.

examples

$ ./char_merge "rebase" "stdin never lies" | cat -e

stdin evrlba$

$ ./char_merge "grep found nothing" "exit" | cat -e

exitgrp foundh$

$ ./char_merge | cat -e
