Recall the deterministic selection algorithm for the median that we saw in class $($Lecture $8,$ but see lecture note $7).$ In there, to compute the $$approx$-$median$($element within the middle $40\%),$ we break the elements into small sets of size $5,$ compute the median for each small set, and then output the median of these n$/5$ medians as the $$approx$-$median$.($a$)$ If instead of breaking into small sets of size $5,$ we break into small sets of size $3$: i$.$ Will the $$approx$-$median$$ we get in this way still be in the middle $40\%?$ Find k$,$ such that the $$approx$-$median$$ we get will be guaranteed to be in the middle k portion. For example, if it is guaranteed to be in the middle $40\%,$ then k $=25.$ Justify your answer, and k should be as tight $($small$)$ as possible. ii$.$ Will the deterministic selection algorithm be still correct in this case? Briefly justify your answer. iii. Give a recurrence relation for the runtime of this version of the deterministic selection algorithm. Can we still argue that it is in linear time? Justify your answer.
