Binary search tree construction Doubt
What is the worst case time complexity to construct a binary search tree.??? Now i know ,that if a BST is left or rightskewed, searching an element takes O(n) time.so suppose i want to insert 10,25,30,35,40 in a bst.. it will be completely right skewed.. So when ... so overall work =0+1+2+...+(n1)=N(n1)/2= O(n2) Am i correct here?? or it is O(nlogn)

ME doubt
I.waiting time gets longer if short process,falls behind long process II.it is always not good for time sharing system,where each process gets equal time share write true/false my question is 2nd one may not be true,if arrival time is same,then order really does not matter everyone is getting a share in slice so my answer is TF, is it correct answer given TT
