String fileName is read from input. The try block opens a file named fileName for output. Three integers are read from input, and each integer is written into the file. Write the finally block to perform the following tasks, if the output file is open:

Write to the file "Number of input values read: $",$ followed by valueReadCount and a newline.

Close the file.

Ex: If the input is celeryoutput. txt $3247,30,$ then celeryOutput.txt contains:

$32$

$47$

$30$

Number of input values read: $3$

Ex$.$ If the input is output. txt bad $4730,$ then output.txt contains:

Number of input values read: $0$

Ex$.$ If the input is $/$nofile$.$txt$,$ then the output is:

Error!
