Suppose an array contains n elements. The elements is in the range 109. We want to know, for every element in the array, the position of the leftmost element that is smaller than that one.

An example:

The array: 20 3 10 5 1 9 100

Answer: 0 0 2 2 0 2 1

Can this problem be done in O(n)?

  1. How do you choose teammates for any team contests like ICPC regional? What is your topmost priority when choosing a teammate?

  2. During a team contest what is your strategy? Do you and your teammates divide problems among yourselves and solve individually or you try to solve one problem at a time but together?

  3. Some suggestions about team training, like what type of problems do u solve when you are practising as a team?

Lots of experienced coders are here. It will be helpful for many of us who're new if u give some suggestions.

PS: I've participated in two local team contests and those memories are not very pleasant.
