String-1 > conCat
prev  |  next  |  chance

Given two strings, append them together (known as "concatenation") and return the result. However, if the concatenation creates a double-char, then omit one of the chars, so "abc" and "cat" yields "abcat".

conCat("abc", "cat") → "abcat"
conCat("dog", "cat") → "dogcat"
conCat("abc", "") → "abc"

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

public String conCat(String a, String b) { }
