Leecode brush questions everyday 2 Title Description move zero Given an array num, write a function to move all zeros to the end of the array while maintaining the relative order of nonzero elements. Please note that you must operate on the array in place without copying it. Example 1: Input: num = [0,1,0,3,12] […]

Leetcode determines whether paths intersect
order This paper mainly records whether the paths of leetcode intersect subject Give you a string path, where the value of path[i] can be’n’,’s’,’e’or’ W ‘, which means moving one unit north, South, East and west respectively. The robot starts from the origin (0, 0) on the twodimensional plane and walks according to the path […]

Leetcode merges two ordered arrays
order This article mainly records the merging of two ordered arrays of leetcode subject Here are two ordered integer arrays nums1 and nums2. Please merge nums2 into nums1 to make nums1 an ordered array. explain: The number of elements initializing nums1 and nums2 is m and N respectively. You can assume that nums1 has […]

The kth missing positive integer of leetcode
order This paper mainly records the kth missing positive integer of leetcode subject Give you a strictly ascending array of positive integers arr and an integer K. Please find the kth missing positive integer in this array. Example 1: Input: arr = [2,3,4,7,11], k = 5 Output: 9 Explanation: missing positive integers include [1,5,6,8,9,10,12,13,…]. […]

Fibonacci number of leetcode
order This paper mainly records the Fibonacci number of leetcode subject Fibonacci numbers are usually represented by F (n), and the sequence formed is called Fibonacci sequence. The sequence starts with 0 and 1, and each subsequent number is the sum of the previous two numbers. That is: F(0) = 0, F(1) = 1 F (n) […]

Whether leetcode can form an arithmetic sequence
order This article mainly records whether leetcode’s judgment can form an arithmetic sequence subject Give you an array of numbers arr. If the difference between any two adjacent terms in a sequence is always equal to the same constant, then this sequence is called an equal difference sequence. If the array can be rearranged to […]

Moving zero of leetcode
order This article mainly records the moving zero of leetcode subject Given an array num, write a function to move all zeros to the end of the array while maintaining the relative order of nonzero elements. Example: Input: [0,1,0,3,12] Output: [1,3,12,0,0] explain: You must operate on the original array and cannot copy additional arrays. Minimize […]

Most elements of leetcode
order This article mainly records most elements of leetcode subject Given an array of size n, find most of its elements. Most elements refer to elements that appear more than ⌊ n/2 ⌋ in the array. You can assume that the array is non empty and that there are always many elements in a given […]

Rearranging array of leetcode
order This paper mainly studies the rearrangement array of leetcode subject Here is an array nums. There are 2n elements in the array, which are arranged in the format of [x1, X2,…, xn, Y1, Y2,…, yn]. Please rearrange the array in the format of [x1, Y1, X2, Y2,…, xn, yn] and return the rearranged array. […]
