Write a function Brackets(int n) that prints all combinations of well-formed brackets. For Brackets(3) the output would be ((())) (()()) (())() ()(()) ()()()
Write a function to get maximum consecutive sum of integers from an array.
You are given an n by n array filled with '0's, and you have to set randomly X number of '1's in that array. Looping and generating x random number doesn't work as you might get the same random number (especially as X gets closer to n*n, collisions will become more likely in which case you'll loop for a very long time before filling all the '1's). All positions must have the same probability to get selected, and the array might be huge.
Given a list of n numbers. All numbers except one are unique. Find the number with duplicate entry.
If you can understand how the game performs, you will find answer very quickly.
List all anagrams in a file. Assumptions: case-insensitive, a-z characters only, one word per line. For example, if the file contains dog, cat, ddd, goo, act, god -- output dog, god, act, cat
Find the minimum depth of binary search tree
Find the min and max in an array. Now do it in less than 2n comparisons. (they were looking for the solution that finds both max and min in about 3/2 n comparisons).
