Hackerank Challenges: Two Strings

Hello friends, if you found this article then you must be looking for something, today we will be solving a problem I found on Hackerank, and I encourage you to please look at the problem before prying into the solution. Without much Ado, let’s get started.

Problem

Given two strings, determine if they share a common substring. A substring may be as small as one character.

Example

s1 = 'and'
s2 = 'art'
These share the common substring a.
s1 = 'be'
s2 = 'cat'
These do not share a substring.

Function Description

Complete the function twoStrings in the editor below.
twoStrings has the following parameter(s):
* string s1: a string
* string s2: another string

Returns

* string: either YES or NO

Input Format

The first line contains a single interger p, the number of test cases.
The following p pairs of lines are as follows:
* The first line contains string s1.
* The second line contains string s2.

Output Format

For each pairs of strings, return YES or NO

Sample Input

2
hello
world
hi
world

Sample Output

YES
NO

Explanation

We have p=2 pairs to check:
1. s1 = "hello", s2 = "world". The substrings "0" and "1" are common to both strings.
2. a = "hi", b = "world". s1 and s2 share no common substrings.
