After three successive calls to function F() which puts "Hey" to output, what entire output appears?

The function F() outputs the string "Hey" each time it is called. When you call the function three times in succession, it will execute three times and produce the string "Hey" during each call.

Since there are no additional instructions or parameters provided that would alter the output format (such as a newline or space), the output from these three successive calls will be concatenated together without any separators. Therefore, the final output will be "HeyHeyHey", which represents the three instances of "Hey" combined sequentially.

Overall, the correct answer reflects the total output generated by those three calls to the function without any modification to spacing or separation between the instances of "Hey".
