Given a string and number k, write a program to find the lexicographically smallest substring of size k. Note: This problem can also be asked as find the lexicographically largest substring of size k...
Given a dictionary (list of words) and an input string K. Find the largest word in the dictionary which can be obtained by deleting a few characters in the input string K. Example: Dictionary:...
Objective: Given two strings, write a program to check if any of the given string is a subsequence of another string. Example if given strings are A and B then EITHER A is subsequence...
Objective: Given an array of string, write a program to find the word in the array which appears the maximum number of times. Example: Input: [Algorithms, String, Integer, Integer, Algorithms, String, Integer, Algorithms, String,...
Objective: Given an array of integers, write a program to count all the pairs with the given sum. Example: Given array: [1, 5, 7, 1, -1], Sum= 6 Total Pairs: 3 Note: pairs are...
Objective: Given an array of integers, and k. Write a program to find indexes of two elements in an array which sum is equal to K. Example: Given array: [5, 4, 7, 3, 9,...
Objective: Given two sets of elements, find the sum of all distinct elements from the set. In other words, find the sum of all elements which are present in either of the given set. ...
Objective: Given a linked list in which nodes are sorted in ascending order. Write an algorithm to insert a given node into the linked list so that all the nodes in the list will...
Objective: Given an array of integers with duplicates, write a program to print unique elements in the array in sorted order. Example: Given Input: [6, 1, 8, 5, 2, 10, 17, 25, 6, 5,...
Objective: Given a list of intervals with start and end for each interval. You have given a value V, write an algorithm to find the number of intervals in which the value V lies. ...
Objective: Given two sets of integers, write an algorithm to print the sum of overlapping elements in two sets. Note: Elements in each set are unique or there are no duplicates within a set....
Objective: Given two coordinates (x1, y1) and (x2, y2). Write a java program to construct a line equation that passes through the given coordinates. Line Equation: Given two coordinates (x1, y1) and (x2, y2)...
Objective: Given a two-dimensional array, write a program to print all middle elements of the array. Or In other words, print all the elements from the array except boundary elements. Example: int [][] grid...
Objective: Given a two-dimensional array or matrix, Do the depth-First Search (DFS) to print the elements of the given matrix. Implement the Depth-first traversal in a recursive manner. Example: int [][] grid = new...
Objective: Given two integers, write an algorithm to calculate the hamming distance between the integers. Hamming Distance: Hamming distance between two integers is the number of positions at which the bits are different. Example:...
