I'm using the
Code:
read

command to read 3 inputs, namely num1, num2, and num3. I want to write a while loop that repeatedly asks for the correct number of inputs, which is 3.

Here's the pseudocode:
read user input here (must be 3)
while the number of inputs entered is less than or greater than 3, ask again for input.
Once it exits the while loop, do the rest of the script's purpose.
