Question 7

The algorithm will make use of a function, contains, that compares two strings and checks
if the second string contains the first string. For example, calling the function with (“fox”,
“foxhound”) this would return true.
The function needs to:
* Take two strings as parameters, string1 and string2
* return true if string1 is contained within string2, or both strings are identical
* return false if string1 is not contained within string2
Write, using pseudocode, the function contains.

Answer 7

function contains(string1, string2)
wordInside = false
for i = 0 to (string2.length – string1.length)
if string2.substring(i, string1.length) ==
string1 then

wordInside=true
endif
next i
return wordInside
endfunction
