**This is an algorithm trace task. No implementation is required.**

Read the following algorithm.

**(Ai)** Copy and complete the table below to show successive values of each of the variables when the input data is 3, 1, 1. [10]

**(Aii)** Copy and complete the table below to show the results of your trace. [1]

**(B)** The above algorithm produces a pattern for entering numbers into a square array. Use this pattern to complete a copy of Table 2.3 if the input is 7, 3, 2. [9]

**(Ci)** Explain what would happen if the input data were 8, 1, 1. [2]

**(Cii)** Explain how to modify the algorithm so that it provides an appropriate response to this data. [3]
