I always loved its understated elegance. After that n-1th element is increased by 1 on alternate steps until it reaches the value at element 0. It is given that we are only allowed to replace the value of an element of the array with its adjacent element, So X should be one of the elements of the array.Also, as we need to make changes as minimum as possible X should be the maximum occurring element of the array. Once we find the value of X, we need only one change per non-equal element (elements which are not X) to make all elements of the array equal to X. If two asteroids will collide, how can we call it?

This question has nothing to do with "C", "C++" specifically (which are different languages anyway), and you should remove hashmap and data-structure tag too, It is a pure algorithm question. (sum(arr) + k) / n. If there is an element in the array which is already greater than this value then the answer does not exist otherwise print Yes. Examples: If its possible to make all the array elements equal with the given operation then print Yes else print No.Examples: Input: arr[] = {18, 30, 54, 90, 162}Output: YesExplanation:We can perform following operations:162 X 5 = 81090 X 3 X 3 = 81054 X 5 X 3 = 81030 X 3 X 3 X 3 = 81018 X 5 X 3 X 3 = 810Input: arr[] = {18, 36, 58, 90, 162}Output: NoExplanation:There is no way you can make all elements equal.

So if you had any approach to a solution, kindly share it. bitwise XOR with 2^x is inversion of x-th bit. perform arr[x] -=1 and arr[y] += 1). Does the order of elements does not matter? The target cannot be greater than the smallest element in A. Your task is to make all the elements of the given array equal in a minimum number of 'moves'. Given an integer n, the length of the array. When N = 1, array has only a single element, so the number of steps required = 0. and When N = 2, number of steps required equal to M, Time Complexity: O(1)Space Complexity: O(1). This article is being improved by another user right now. How many 6-digit numbers are there that have at most 2 different digits? You need some possibility of testing, which you don't specify. For further actions, you may consider blocking this person and/or reporting abuse. If all the items are the same we stop and return success, otherwise we keep going. Product of Two Elements in Array - Take Gifts From the Richest Pile - Make Array 0 by Subtracting Equal Amounts - Sort Characters By Frequency - Smallest Number in Infinite Set - Last Stone Weight Minimum operation to make all elements equal in array, Make all array elements equal to 0 by replacing minimum subsequences consisting of equal elements, Minimum cost to equal all elements of array using two operation, Minimum sum of values subtracted from array elements to make all array elements equal, Make all array elements equal by reducing array elements to half minimum number of times, Minimum number of bits of array elements required to be flipped to make all array elements equal, Minimum increments to make all array elements equal with sum same as the given array after exactly one removal, Minimum swaps of similar indexed elements required to make all elements of one of the two given arrays equal, Minimum increment and decrement by K of each pair elements required to make all array elements equal, Minimize subtraction followed by increments of adjacent elements required to make all array elements equal, Learn Data Structures with Javascript | DSA Tutorial, Introduction to Max-Heap Data Structure and Algorithm Tutorials, Introduction to Set Data Structure and Algorithm Tutorials, Introduction to Map Data Structure and Algorithm Tutorials, What is Dijkstras Algorithm? we can walk through all bit numbers and count how many array values contain bit 1 at place x (say m ones) and the rest (n-m) contains bit 0 at place x. In one move, you can increment n - 1 elements of the array by 1. Then the entire array becomes equal.So the pattern followed by the last element is(0, 0, 0.., 0) till (N 4)th element becomes 1 which is n-4 stepsand after that,(0, 0, 1, 1, 2, 2, 3, 3, 4, 4, M 1, M 1, M) which is 2*m + 1 steps.So the Final Result becomes (N 3) + 2 * MThere are a few corner cases which need to be handled, viz. Does the policy change for AI-generated content affect users who (want to) How do I check if an array includes a value in JavaScript? So the answer would be 4 steps. It also means the inverse, that x should move down if there are more elements below x than above. By using our site, you DEV Community 2016 - 2023. Most upvoted and relevant comments will be first. We need to find the minimum number of operations required to make all array elements equal. Way to judge if two Arrays are identical? (Jump to: Problem Description || Code: JavaScript | Python | Java | C++). A film where a guy has to convince the robot shes okay. The goal is to make all the elements of the array equal. However, in the implementation, there is a small bug i.e. Has any head of state/government or other politician in office performed their duties while legally imprisoned, arrested or paroled/on probation? "Murder laws are governed by the states, [not the federal government]." This means that x should naturally move up if there are more elements above x than below. Why would power be reflected to a transmitter when the antenna port is open, or a higher impedance antenna connected? Replace the value of one element of the array by one of its adjacent elements. Connect and share knowledge within a single location that is structured and easy to search. For Example. By using our site, you Built on Forem the open source software that powers DEV and other inclusive communities. After reading the inputs we create a set of numbers that can be created from reducing each b from a, so for the example provided we get: Now we find the intersection set, and take the highest number from it. For example: Second, if you were told the final value, how would you solve the puzzle? Given an integer array nums of size n, return the minimum number of moves required to make all array elements equal. In a single operation, any element of the array can be either multiplied by 3 or by 5 any number of times. We could, indeed. DEV Community 2016 - 2023. Examples: Constraints: n == nums.length 1 <= nums.length <= 10^5 -10^9 <= nums [i] <= 10^9 Idea: For C++, we can use nth_element to find the median in O(N) time without having to fully sort nums. How is Canadian capital gains tax calculated when I trade exclusively in USD? Connect and share knowledge within a single location that is structured and easy to search.

By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. You are provided with an array of n integers. Once unpublished, all posts by seanpgallivan will become hidden and only accessible to themselves. In order to even the entire array, we'll just need another n / 2 operations to move the right side down 1 and the left side up 1. You are allowed to make any number of steps. After this number is found we count the number of operations to reach that number for each a and b pair. Thus the only difference between the two formulas is the - 1 present in the odd version, which is basically the rounding error if n is odd, and can be corrected by flooring the result. Give the answer modulo 109+7. For further actions, you may consider blocking this person and/or reporting abuse. Does the order of elements does not matter? But that's when n is odd and the middle is conveniently a point. At the end, I have to Return the minimum number of operations required. If you then think of the triangle of moves that have to be made, you can note that the area of said triangle is 1/8th the area of the box, or 2n^2 / 8, or n^2 / 4.
