The output when the recursive method is executed is

  • WATC
  • WAT
  • WA
  • W

How to determine the code output?

The flow of the code is to print the characters of the string from -1 index to the 0 index.

The string passed to the function is "WATCH"

So the code would print "WATC" to "W", each on a new line

Hence, the output when the recursive method is executed is

  • WATC
  • WAT
  • WA
  • W
