prev  |  next  |  chance

Given 3 strings, compare the all corresponding characters of all 3 strings and return similar characters at the similar indexs. The length of the strings could be different.
Hint: since you don't know the length of strings you should use loop.


getSimilars("ab", "ab", "ab") → "ab"
getSimilars("ab", "ac", "ad") → "a"
getSimilars("a", "ab", "abc") → "a"

...Save, Compile, Run (ctrl-enter)

public String getSimilars(String s1, String s2, String s3) { }
