C check for duplicates in array
WebThis tutorial will discuss about a unique way to check if an array is a subset of another array in C++. Now we want to check if the second array arr2 is a subset of first array arr1. For this, we are going to use STL algorithm std::includes () which accepts 2 ranges as arguments. Basically std::includes () function will accept 4 arguments i.e. WebYou could sort the array in O(nlog(n)), then simply look until the next number. That is substantially faster than your O(n^2) existing algorithm. The code is also a lot cleaner. Your code also doesn't ensure no duplicates were inserted when they were re-entered. You need to prevent duplicates from existing in the first place.

WebThis post will discuss how to find all duplicates in an array in C#. 1. Using Enumerable.GroupBy Method The idea is to group the elements based on their value and then filter the groups that appear more than once. This can be done with LINQ’s Enumerable.GroupBy () method. WebTherefore it is must to check if a given index position exists in the array or not before accessing element at that index position. To check if index position is valid or not, first we need to fetch the size of the array, and then we can check, if the given index position is either greater than or equal to zero and less than the size of the array.
