seq_scan

Strings: walking and searching16

Objective

Write a program that receives two strings and checks, case-insensitively, whether every character of the first string appears in the second string in the same relative order.

Steps

The program expects exactly two arguments.
If the number of arguments is not 2, print wrong number of arguments followed by a newline.
Scan the second string left to right and attempt to match each character of the first string in order, ignoring case differences.
If all characters of the first string are matched in order, print the first string followed by a newline.
Otherwise, print only a newline.
