Max Distance between two occurrences of the same element
Given an array of integers where elements may be repeating in the array. Find the maximum distance between two occurrences of the same element in the array.
Maximum consecutive integers present in an array
Given an array of integers. Find the maximum number of consecutive integers present in the array. For example, if the array is: int arr[] = { 2, 24, 22, 60, 56, 23, 25}; Then the answer should be 4, because there are 4 consecutive integers present in the array (22, 23, 24, 25).
Recursive Bubble Sort
Give the recursive implementation of the Bubble Sort algorithm
Find two elements in an array whose sum is x
Given an array of integers and a number x. check if there exists two elements in the array whose sum = x.
Find numbers with more than k-bits in their binary representations
Given an array of unsigned integers, print all the numbers that have more than k bits set in their binary representation. For example, if k = 2, and input array is: int arr[] = {2, 1, 15, 9, 7, 14, 32, 127}; Then the output should be: 15 7 14 127 Because all of these […]
Water overflowing from glass arranged in form of triangle
Glasses are arranged in the form of triangle (on top of each other) as shown below: 1 2 3 4 5 6 7 8 9 10 ……………….. …………………. Liquid is poured into 1st glass (Glass no. 1). When it is full, then extra liquid will flow into the glasses 2 and 3 in equal quantities. […]
Maximum (or minimum) sum of subarray of size k
Given an array of n integers, find the sub-array of length k with maximum sum. For example, Input Array: {6, 4, 3, 5, 1, 9, 2} k:3 Output: 15 (sum of sub-array 5, 1, 9)
Consecutive numbers with sum equal to n
Given a positive integer n, print the consecutive numbers whose sum is equal to n. For example, n = 20 Output: 2, 3, 4, 5, 6 (because 2+3+4+5+6+7 = 20) n = 29 Output: 14, 15
Check duplicate parenthesis in an expression
A valid mathematical expression can also have duplicate parenthesis as shown below: ((a+b)) (((a+(b)))+(c+d)) Write code to find if an expression has duplicate parenthesis. You may assume that expression does not have any white spaces.
Next greater element
Print Next Greater Element for every element in the array. The Next greater Element of element x is first greater element on its right side. Elements for which no greater element exist, next greater element is -1. Example: – For any array, rightmost element always has next greater element as -1. – All elements of […]
