Suppose that $\backslash$alpha is a fraction in the range $0<\backslash$alpha $<1.$ Show how to generalize the lower$-$bound argument for insertion sort to consider an input in which the $\backslash$alpha n largest values start in the first $\backslash$alpha n positions. What additional restriction do you need to put on $\backslash$alpha $?$ What value of $\backslash$alpha maximizes the number of times that the $\backslash$alpha n largest values must pass through each of the middle $(12\backslash$alpha $)$n array positions?
