Answer
Iteration is first used at Line number 6, where the algorithm checks the condition of the while loop.

Answer
When the user inputs 10, the output will be 2 since the algorithm will perform the integer division: 10 DIV 3 which evaluates to 3. The loop continues until 'a' becomes 0.
Step 3
In the algorithm in Figure 2, what is the largest possible value of the variable counter when the user input is 36?

Answer
The largest possible value of the variable counter when the user input is 36 is 5, as after each iteration 'a' is reduced by integer division of 3.
