prev  |  next  |  chance

Given an String "word" and a String "letter", recursively return the total number of times the letter appears in the word. Case-sensitivity matters!


recur_letterCount("Robert", "b") → 1
recur_letterCount("Boltz", "z") → 1
recur_letterCount("Problem", "s") → 0

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

public int recur_letterCount(String word, String letter) { }
