A student has been asked to create a simple guessing game program. This program will generate a random integer value between 1 and 100. It will then repeatedly prompt the user to input an integer value until they input the randomly generated value. The student has written a structured English description: step 1 - randomly generate an integer value between 1 and 100 inclusive step 2 - prompt the user to input an integer value step 3 - output an appropriate message if the value input was too high; then repeat from step 2 step 4 - output an appropriate message if the value input was too low; then repeat from step 2 step 5 - output an appropriate message if the value input was the same value that was randomly generated; then end the program. Write a pseudocode algorithm from this structured English description. Assume no input validation is needed.
