Given a TV remote, write a script that would give directions to input some letters. Starting from the upper left-hand corner. If the buttons were in 3 columns, and you wanted to type "feed", you would want the output of the program to say "right, right, down, PRESS, left, PRESS, PRESS, left, PRESS"
Implement string rotateString(string input, int amt)
Using Collabedit, write a program to find the index of the first non-repeated character in a java string.
Nothing unexpected, I solved all the problems but I think I was too slow on the first one, which goes like: Given an array of numbers, they are arranged so that the a[0] is in the 1st bucket, a[1]a[2] are in the 2nd bucket, a[3]a[4]a[5] is in the 3rd bucket and so on. The question is then: given a number, you need to return if it is in any bucket or not.
Given a string with parenthesis like "()()(()(()()", check to see if there are matching pairs. If there are matching pairs, return true, else return false. For example, ()()() returns true, ()()()) returns false.
Find Kth smallest element in a BST.
Generate a new array from an array of numbers. Start from the beginning. Put the number of some number first, and then that number. For example, from array 1, 1, 2, 3, 3, 1 You should get 2, 1, 1, 2, 2, 3, 1, 1 Write a program to solve this problem.
Write a function that takes 2 arguments: a binary tree and an integer n, it should return the n-th element in the inorder traversal of the binary tree.
The first coding question was to determine whether a list of integers with size N, contains all the numbers from one to N.
Given a sorted array, where each element but one occurs only once, return the element that repeats. (For example, given 1, 2, 3, 3, 4, return 3. Given 1, 2, 3, 4, 6, 6, 7, 8, 9, return 6.)
