Output:The duplicate elements are 1 and 4 练习这个问题 相关帖子: 在不使用任何额外空间的情况下查找数组中出现的两个奇数元素 对于包含的输入n元素,我们可以使用散列法法解决这个问题O(n)时间。这个想法是遍历数组并保持哈希表中每个元素的频率。然后,在处理完每个数组元素后,返回频率为 2 的元素。这种方法的问...
Find duplicates where there is at least one duplicate from the specified folder. (includes subfolders) For example: *.jpg dupe-from:"C:\My Photos" dupe:size Added a dupe-min: search function. Find duplicates where the number of duplicates is greater than or equal to the specified minimum ...
To find duplicate files, given input of String array is quite easy. Loop through each String and keep a HashMap of Strings to Set/Collection of Strings: mapping the contents of each file to a set of paths with filename concatenated. For me, instead of given a list of paths, I was gi...
Find Duplicate File in System Given a list of directory info including directory path, and all the files with contents in this directory, you need to find out all the groups of duplicate files in the file system in terms of their paths. A group of duplicate files consists of at least two...
