The obvious solution, that uses log(n) space, (n is the number of nodes) is the algorithm you mentioned. If you were only permitted to complete at most one transaction (ie, buy one and sell one share of the stock), design an algorithm to find the maximum profit. result = sb.toString(); sb.append(count); ... For eg : A = [ 2, 3, 3, 3] We count the number of 1s for each bit position. Bookings contain an arrival date and a departure date. both indicate a queen and an empty space respectively. Arrays in Java; Write a program to reverse an array or string ; Program for array rotation; Arrays in C/C++; Noble integers in an array (count of greater elements is equal to value) Difficulty Level : Medium; Last Updated : 09 Nov, 2020; Given an array arr[], find a Noble integer in it. It seems like Solution 1 is the only solution that addresses the original problem – Solution 2 allocates a new array and Solution 3 only counts the number of duplicates. extreme ends, Bookmarked, Keeping window size having zeroes <= B, Bookmarked, (A+B) > C by sorting the array, Bookmarked, Reverse Half and merge alternate, Bookmarked, Doing Min in O(1) space is good one, Bookmarked, Do read brute force and think in terms of stack, Bookmarked, Finding Min is reverse of current logic, Bookmarked, Backtracking general algo, Use Map for checking duplicates, Bookmarked, Either use hashmap or skip continuous elements in recursion function, Bookmarked, can maintain 2-D array to keep true/false whether start-end is palindrome or not (DP), Bookmarked, Either use visited array or remove integer from input array then add back while backtracking, Bookmarked, Other Solution of using reverse of (N-1) and prefixing 1 is good, Bookmarked, Use Maths plus recursion, first digit = k/(n-1)!+1, Bookmarked, 3 conditions - element 0, sum 0 or sum repeated, Bookmarked, Either use n^3 solution using 2 pointers and hashSet for unique sets or or use customised sorting plus hashSet, Bookmarked, check row, col and box, keep different maps, Bookmarked, Use 2 pointers and map to keep count of characters included - plus and minus, Bookmarked, Slope should be same, Consider first point as start and rest as end and create map and repeat; Keep edge cases like which slopes are valid and others keep in diff variables, Bookmarked, Brute force but just using hashmap for string match, Bookmarked, Create a min heap and loop through n^2 pairs, Bookmarked, T(n) = n-1Cl*T(l)*T(r), where r = n-1-l, Bookmarked, Good Question plus also know inorder using 1 stack, Bookmarked, Can be done without extra space as well, Bookmarked, Can be done in O(n) space with sorted array, Bookmarked, Can be done in O(n) space with array, Bookmarked; Morris Algo - attaching current to inorder predecessor, Can be done in O(n) space with array, rest concept is same, Bookmarked, mod can be used even before number is formed, Bookmarked, If Space was not constant then using queue is very easy, Bookmarked, either use count of unique flag at each node, update the child's property and not current node, Bookmarked, Can be solved using stack or recursion, Bookmarked, Solve it like a puzzle, good question. Given a non-empty array of integers nums, every element appears twice except for one. Given a word, find the lexicographically greater permutation of it. Given an unsorted integer array, find the first missing positive integer. You've probably already seen this in other posted solutions.However, if we take advantage of bitwise operations, we may be able to manage all the 32 counters "collectively". The count-and-say sequence is a sequence of digit strings defined by the recursive formula:. Then find mod 3 of each of them. III -- General case with 32-bit numbers. Example: if n = 2, Question: The n-queens puzzle is the problem of placing n queens on an n×n chessboard such that no two queens attack each other. The bit positions having mod 3 equal to one are the bits that are set due to the number occurring once. Repeat and Missing Number Array: You are given a read only array of n integers from 1 to n. Each integer appears exactly once except A which appears twice and B which is missing. Instead of using a boolean array to track the matched positions, we need to track the actual matched words. Now it's time to generalize our results from 1-bit number case to 32-bit integers. Note: The sequence of integers will be represented as a string. results += f"{count}{val}" For 11 it would be 21; for 21 it would be 1211; for 1211 it would be 111221; Given n find the nth count and say string.
