Question
SA5: Fill in the squares to indicate whether each statement is TRUE or FALSE:
TRUE FALSE Mergesort runs in O(NlogN)
TRUE FALSE
TRUE FALSE
TRUE FALSE
TRUE
Mergesort must complete approximately N passes before a list is sorted
Mergesort is somewhat faster than selection sort, but in the same Big O
function family
On each pass, mergesort will need to perform approximately logN
comparisons
FALSE There is no comparison sorting algorithm in a faster function family
than mergesort (assuming no prior knowledge about the unsorted items
and no quantum computers)
