<lang euphoria>sequence first, second

integer x

first = "qwertyuiop"

-- Determining if the first string starts with second string

second = "qwerty"

if match(second, first) = 1 then

printf(1, "'%s' starts with '%s'\n", {first, second})

else

printf(1, "'%s' does not start with '%s'\n", {first, second})

end if

-- Determining if the first string contains the second string at any location

-- Print the location of the match for part 2

second = "wert"

x = match(second, first)

if x then

printf(1, "'%s' contains '%s' at position %d\n", {first, second, x})

else

printf(1, "'%s' does not contain '%s'\n", {first, second})

end if

-- Determining if the first string ends with the second string

second = "uio"

if length(second)<=length(first) and match_from(second, first, length(first)-length(second)+1) then

printf(1, "'%s' ends with '%s'\n", {first, second})

else

printf(1, "'%s' does not end with '%s'\n", {first, second})

end if</lang>

Output:

<pre>'qwertyuiop' starts with 'qwerty'

'qwertyuiop' contains 'wert' at position 2

'qwertyuiop' does not end with 'uio'

</pre>
