int end = m*n-1; (Remade) Rotate Array | Arrays | Leetcode 189 Nideesh Terapalli. Easy. This can be done in O(n) time by doing a single traversal of given array. Example 1: Input: [3, 1, 4, 1, 5], k = 2 Output: 2 Explanation: There are two 2-diff pairs in the array, (1, 3) and (3, 5). Remember solutions are only solutions to given problems. down++; Intersection of Two Arrays II-LeetCode Given two arrays, write a function to compute their intersection. Find peak in 2d array leetcode. You may try to solve this problem by finding the row first and then the column. In a two-dimensional array of n * m, each row is sorted in ascending order from left to right, and each column is sorted in ascending order from top to bottom. int mid=(start+end)/2; Easy #10 Regular Expression Matching. Mohamed Abdullah is a new contributor to this site. The time complexity of the above solution is O(nLogn) if a O(nLogn) sorting algorithm like Merge Sort, Heap Sort, .. etc is used.. Do not allocate extra space for another array, you must do this in place with constant memory. Since we know the numbers are in increasing order. There are two sorted arrays nums1 and nums2 of size m and n respectively.
