//Given two strings, return true if either of the strings appears at the very end of the other string, ignoring upper/lower case differences (in other words, the computation should not be "case sensitive"). Note: str.toLowerCase() returns the lowercase version of a string.

//endOther("Hiabc", "abc") → true

//endOther("AbC", "HiaBc") → true
