If you have a sorted array that is initialized with size 100, the values stored would be for example 1, 2, 3,.... ect. Describe an algorithm that would check if there is a duplicate number and if so return it.
Came up with a program to take a string and printed the characters that appear more than once in the exact order as they are in the original string.
Write a program to convert a string written as JAVA variable to C++ variable and vice-versa. Input : this_is_a_variable Output: thisIsAVariable
Given a tree where every right node is a leaf, meaning that it can only extend on the left side, invert it such that the leftmost node is now the root, and all of the previous left nodes are now on the right side. The former right nodes will be on the left side.
Given an array with duplicate elements give an algorithm to get the count of distinct elements in the array
Asked a question to determine the sum of an array of integers. Recursive problem.
Write a program that takes an integer and prints out all ways to multiply smaller integers that equal the original number, without repeating sets of factors. In other words, if your output contains 4 * 3, you should not print out 3 * 4 again as that would be a repeating set. Note that this is not asking for prime factorization only. Also, you can assume that the input integers are reasonable in size; correctness is more important than efficiency. PrintFactors(12) 12 * 1 6 * 2 4 * 3 3 * 2 * 2
They asked to write a function that takes a string and check if it is a number. The second question was given a sorted array that has been rotated, find a number in that array {6,7,1,2,3,4,5}
2. /** * A tournament tree is a binary tree * where the parent is the minimum of the two children. * Given a tournament tree find the second minimum value in the tree. * A node in the tree will always have 2 or 0 children. * Also all leaves will have distinct and unique values. * 2 * / \ * 2 3 * / \ | \ * 4 2 5 3 * * In this given tree the answer is 3. */ class Node { Integer value; Node left, right; Node(Integer value, Node left, Node right) { this.value = value; this.left = left; this.right = right; } } class Solution { /** * This should return the second minimum * int value in the given tournament tree */ public static Integer secondMin(Node root) { } }
