Merging sorted arrays is a fundamental problem in computer science. The task is to combine two sorted arrays into one sorted array, maintaining the order. The Merge Sorted Array presents this classic problem with a twist — you are asked to merge the arrays in-place. This means that instead of using extra space, you must … Read more
Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The order of the elements may be changed. Then return the number of elements in nums which are not equal to val. Consider the number of elements in nums which are not equal to val be k, to get accepted, you need to do the following things: Custom Judge: The judge will test your … Read more
