Warmup-2 > last2
prev  |  next  |  chance

Given a string, return the count of the number of times that a substring length 2 appears in the string and also as the last 2 chars of the string, so "hixxxhi" yields 1 (we won't count the end substring).


last2("hixxhi") → 1
last2("xaxxaxaxx") → 1
last2("axxxaaxx") → 2

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

public int last2(String str) { }
