William has two numbers $$$a$$$ and $$$b$$$ initially both equal to zero. William mastered performing three different operations with them quickly. Before performing each operation some positive integer $$$k$$$ is picked, which is then used to perform one of the following operations: (note, that for each operation yo...

NoteLet us demonstrate one of the suboptimal ways of getting a pair $$$(3, 5)$$$: Using an operation of the first type with $$$k=1$$$, the current pair would be equal to $$$(1, 1)$$$. Using an operation of the third type with $$$k=8$$$, the current pair would be equal to $$$(-7, 9)$$$. Using an operation of the seco...
