Given an array nums of size n, return the majority element. The majority element is the element that appears more than ⌊n / 2⌋ times. You may assume that the majority element always exists in the array. Constraints: n == nums.length 1 <= n <= 5 10^4 10^9 <= nums[i] <= 10^9 Examples: Example 1: Input
Given an integer array nums, move all 0's to the end of it while maintaining the relative order of the nonzero elements. You must do this inplace without making a copy of the array and aim to minimize the total number of operations (assignments). Constraints: 1 <= nums.length <= 10^4 2^31 <= nums[i]
Given an integer array nums, return an array answer such that answer[i] is equal to the product of all the elements of nums except nums[i]. You must solve this problem without using any division operation and in O(n) time complexity. Constraints: 2 <= nums.length <= 10^5 30 <= nums[i] <= 30 The prod
You are given the heads of two sorted linked lists, list1 and list2.\n\nMerge the two lists into one sorted list. The list should be made by splicing together the nodes of the first two lists.\n\nReturn the head of the merged linked list.\n\n Constraints\n\n The number of nodes in both lists is in t
Given a nonempty array of integers nums, every element appears twice except for one. Find that single one. Constraints The array nums will always contain exactly one element that appears only once. Your algorithm should have a linear runtime complexity. Can you implement it without using extra memor
