Construct an Array of Strings having Longest Common Prefix specified by the given Array | Function to find the array of strings.
Marks the ( N + 1 ) th string.
To generate remaining N strings.
Find i - th string using ( i + 1 ) - th string.
Check if current character is b.
Otherwise.
Insert the string.
Return the answer.
Driver Code.
Print the strings"
