Javascript arrays can contain duplicates - which is fine most of the time, but can sometimes cause some issues. For example, if an array is supposed to only contain unique user IDs, but is taken from a data source that may contain duplicates. In these cases, it can seem quite difficult ...
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...
Sample array: [20, 20, 30, 40, 50, 50, 50, 50, 60, 60] After removing the duplicate elements the program should return 5 as the new length of the array Sample Solution: Scala Code: objectScala_Array{deftest(nums:Array[Int]):Int={varindex=1;for(i<-0tonums.length-1){if(nums(...
