Given an array of integers, 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements that appear twice in this array. Could you do it without extra space and in O(n) runtime? Example: Input: [4,3,2,7,8,2,3,1] Output: [2...

与[LeetCode]Find All Numbers Disappeared in an Array几乎一样,不同之处就是找出twice的数。那么我们只要当nums[i]!=i+1时,然后又当nums[nums[i]-1]==nums[i]时,把nums[i]放入set即可。

Use the FILTER function (available in Excel 2021 and Microsoft 365) to find duplicates. Obtain the outcome in an array format by combining FILTER and UNIQUE functions. Enter the following formula in cell E6:=UNIQUE(FILTER(B6:B19,COUNTIF(C6:C17,B6:B19)>0))...
I need to load an array with random integers, however, the numbers need to be unique. The size of the array can vary based on user input, so using a static "if array[0] == array[1]", etc., is not going to work. I'm assuming I will need to do this with a for loop, I'...
