Two Strings - HackerRank Solution.

NOTE: If you are copying my code then its an advice to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of the source code.

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

For example, the words "a", "and", "art" share the common substring . The words "be" and "cat" do not share a substring.

Function Description

Complete the function twoStrings in the editor below. It should return a string, either YES or NO based on whether the strings share a common substring.

twoStrings has the following parameter(s):

• s1, s2: two strings to analyze .

Input Format

The first line contains a single integer , the number of test cases.

The following  pairs of lines are as follows:

• The first line contains string .
• The second line contains string .

Constraints

•  and  consist of characters in the range ascii[a-z].

Output Format

For each pair of strings, return YES or NO.

Sample Input

2
hello
world
hi
world

Sample Output

YES
NO

Explanation

We have  pairs to check:

1. , . The substrings  and  are common to both strings.
2. , .  and  share no common substrings.
