X270: Recursion Programming Exercise: Count Character A
For function countChr()
write the missing part of the
recursive call.
This function should return the number of times that the
letter "A" appears in string "str".
Recall that str.substring(a)
will return the substring of
str
from position a
to the end of str
, while
str.substring(a, b)
will return the substring of str
starting at position a
and continuing to (but not
including) the character at position b
.
Examples:
countChr("ctcowcAt") -> 1
