All operations used to construct algorithms belong to one of three categories: sequential, conditional, or iterative. Below is a list of steps from a variety of algorithms. Determine which category to which each of the steps belong (sequential, conditional, or iterative). If the value of test_grade is between 90 and 100, assign a letter grade of A. Prompt the user for a number, get number from user
Sequential Repeat steps 3-5 until count = 10
If divisor = 0, print error_message
Complete step 1, complete step 2, complete step 3
