Consider an array consisting of ve and +ve numbers. What would be the worst time comparisons an algorithm can take in order to segregate the numbers having same sign altogether i.e all +ve on one side and then all ve on the other ? N1 N N+1 (N*( ... the solution says N1 they are using using first element as pivot but shouldn't we use 0 as pivot hence N should be the answer

binary heap
Consider a binary min heap containing n elements and every node is having degree 2 ( i.e. full binary min heap tree). What is the probability of finding the largest element at the last level ? According to my understanding the largest elemenyt has to be a leaf and since leafs can be on two levels last and second last therefore the probability should be 1/2
