Answer to Question #165140 in Python for raj

Question

Write a program to check the overlapping of one string's suffix with the prefix of another string.Input

The first line of the input will contain a string A.

The second line of the input will contain a string B.Output

The output should contain overlapping word if present else print "No overlapping".Explanation

For example, if the given two strings, A and B, are "ramisgood" "goodforall"

The output should be "good" as good overlaps as a suffix of the first string and prefix of next.

Answer 1

a = 'ramisgood'
b = 'goodforall'


def longestSubstringFinder(string1, string2):
    answer = ""
    len1, len2 = len(string1), len(string2)
    for i in range(len1):
        match = ""
        for j in range(len2):
            if (i + j < len1 and string1[i + j] == string2[j]):
                match += string2[j]
            else:
                if (len(match) > len(answer)): answer = match
                match = ""
    return answer


print(longestSubstringFinder(a, b))
