Assume that you are given the head and tail pointers of a doubly linked list where each node can also have a single child pointer to another similar doubly linked list. There are no cycles in this structure outside of the traditional double links. Write a procedure in C++ that flattens this structure into a single list.
If you have a program that runs slow, how will you improve it to run faster?

Write a function that returns true when number of things (N) can be precisely divided into boxes of 6, 9 and 20 => N = 6x + 9y + 20z
Given a string, find the longest substring T that contains m distinct characters. (need O(n) solution)
what's wrong with the following code : <template type T > T accumulate ( vector<T> in) { T total = in[0]; for (int i =0; i < in.length() ; i++) { total = total + in[i]; } return T }
Given n numbers (P1,P2,P3,.....Pn). Divide them in m contiguous partitions such that the sum of the maximum is minimum. For e.g. (5,1,4,2,3) and m =2 then (5,1)(4,2,3)
