Given the array of strings A, you need to find the longest string S which is the prefix of ALL the strings in the array.
Longest common prefix for a pair of strings S1 and S2 is the longest string S which is the prefix of both S1 and S2.
For Example: longest common prefix of
The only argument given is an array of strings A.
Return the longest common prefix of all strings in A.
A = ["abcdefgh", "aefghijk", "abcefgh"]
A = ["abab", "ab", "abcd"];
Longest common prefix of all the strings is "a".
Longest common prefix of all the strings is "ab".
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
