The array is sorted, so duplicates must be in a consecutive group. Here I used two pointers, one to scan the array, the other to record the unique value. Everytime a unique value is found, record it. The rest of the duplicate values are discarded and overwritten. Time complexity is O(...
Given sorted array A =[1,1,1,2,2,3], Your function should return length =5, and A is now[1,1,2,2,3]. 典型的两指针问题 两个指针指向初始位置,一个指针i开始遍历,记录出现相同数的个数 如果遍历的指针i等于其前面的指针index且cnt个数超过两个,则继续移动遍历的指针 ...
Time Complexity: O(n), traversing through elements of the array.Space Complexity: O(n), using HashSet to store elements. Remove Duplicates from Array Using Sorting In this approach, we first sort the array. When sorted, duplicate elements will be next to each other. We then iterate through...
Removing Duplicate Elements from Array We need to remove duplicate elements from array so that each element only appears once (all the values in the array should become unique). Example Input: [1,2,2,3,4,4,4,5,5] Output: [1,2,3,4,5] Explanation The frequency of each element is sh...
This function returns the array free of duplicate values. The program below shows the ways by which we can use thearray_unique()function to remove duplicate values from an array in PHP. <?php$array=array("Rose","Lili","Jasmine","Hibiscus","Daffodil","Daisy","Daffodil","Daisy","Lili"...
As observed, the duplicate elements from the unsorted arrays are also removed in the same manner as sorted arrays. But here, one additional method is used to sort the unsorted array. It is to be noted that one should check whether the array is sorted or not and then proceed with the nex...
