A school is trying to take an annual photo of all the students. The students are asked to stand in a single file line in non-decreasing order by height. Let this ordering be represented by the integer array expected where expected[i] is the expected height of the ith student in line. You are given an integer array heights representing the current order that the students are standing in. Each hei..

Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The relative order of the elements may be changed. Since it is impossible to change the length of the array in some languages, you must instead have the result be placed in the first part of the array nums. More formally, if there are k elements after removing the duplicates, then the first k elements..

Given an integer array nums, move all the even integers at the beginning of the array followed by all the odd integers. Return any array that satisfies this condition. Example 1: Input: nums = [3,1,2,4] Output: [2,4,3,1] Explanation: The outputs [4,2,3,1], [2,4,1,3], and [4,2,1,3] would also be accepted.Example 2: Input: nums = [0] Output: [0]Constraints: 1

Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the non-zero elements. Note that you must do this in-place without making a copy of the array. Example 1: Input: nums = [0,1,0,3,12] Output: [1,3,12,0,0] Example 2: Input: nums = [0] Output: [0] Constraints: 1

Code Java public int removeDuplicates(int[] nums) { // Check for edge cases. if (nums == null) { return 0; } // Use the two pointer technique to remove the duplicates in-place. // The first element shouldn&#39;t be touched; it&#39;s already in its correct place. int writePointer = 1; // Go through each element in the Array. for (int readPointer = 1; readPointer < nums.length; readPointer++) { //..

My code func removeDuplicates(nums []int) int { if nums == nil { return 0 } k := 0 for _, v := range nums { if v != nums[k] { k++ nums[k] = v } } return k + 1 } I used for loop value output. It starts from array[0]. So if it will be different with value, k will be increased and value will be input there. Simple Code. sample 0 ms submission func removeDuplicates(nums []int) int { if len(nums) < 2..

The nested loop Code Java class Solution { public int removeDuplicates(int[] nums) { // The initial length is simply the capacity. int length = nums.length; // Assume the last element is always unique. // Then for each element, delete it iff it is // the same as the one after it. Use our deletion // algorithm for deleting from any index. for (int i = length - 2; i >= 0; i--) { if (nums[i] == num..

Given an array arr, replace every element in that array with the greatest element among the elements to its right, and replace the last element with -1. After doing so, return the array. Example 1: Input: arr = [17,18,5,4,6,1] Output: [18,6,6,6,1,-1] Explanation: - index 0 --> the greatest element to the right of index 0 is index 1 (18). - index 1 --> the greatest element to the right of index 1..
