http://cs.yale.edu/homes/aspnes/pinewiki/LowerBounds.html WebJul 21, 2024 · You are absolutely right, the bound does not need to be tight. For instance, consider a simple example: finding the smallest integer in an array of n integers. There is an O(1) space and O(n) time algorithm to solve this problem every time. However, this problem reduces to the problem of sorting an array of integers via a reduction in O(1) both ways: ...
