    Any comparison-based sorting algorithm can not run faster then n*log(n) time by comparison-based we mean the we can not access the "guts" of objects, it can only compare objects. To prove the lower bound, we use pigeonhole principle: if there are n pigeons and n-1 holes, two pigeons will end up in 1 hole.

  • Top wing full episodes free downloadThus, we say that the selection sort has a runtime complexity of O(n^2). With insertion sort, we pick a element from the unsorted part of the array, then does a linear search to insert it into the right position in the sort part of the array. It does that n times, one for each element. Thus, the runtime complexity of insertion sort is actually equivalent to selection sort, at O(n^2). ,Why is the best case time complexity for selection sort O(n^2) when it is O(n) for insertion sort and bubble sort? Selection sort does not check if the array is already sorted by an linear-time algorithm.
