In the loop:

Assign a variable with the integer value read from input.

Output the integer value.

Unless the integer value is the last input read, output $"|"$ after the integer output.

After the loop terminates, output a newline.

Ex: If the input is:

$4$

$16,14,12,15$

then the output is:

$16|14|12|15$

Note: An approach to avoid outputting $"|"$ after the last value is to use an if statement in the for loop. The if statement checks if

iterator $i$ is not equal to the last iteration, valCount $-1.$
