countHi


Given a string, compute recursively (no loops) the number of times lowercase "hi" appears in the string. In this example, you will be writing a helper method. Do NOT use the substring method anywhere in your solution. Uncomment the code in the template and then implement the countHiHelper method. countHi("xxhixx") → 1 countHi("xhixhix") → 2 countHi("hi") → 1


countHi("xxhixx") → 1
countHi("xhixhix") → 2
countHi("hi") → 1

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

public int countHi(String str) { }
