WebNow, to check if all string elements of an array matches a given regex pattern, we can use the STL Algorithm std::any_of (). The std::any_of () function accepts the start and end iterators of array as first two arguments. As the third argument, we will pass a Lambda function which accepts a string as an argument and returns true if the given ... WebSo, to check if array has only unique elements, first sort the array using the std::sort () function. Then using the std::adjacent_find () function, check if any two adjacent values are equal in the sorted array. If yes, then it means all the elements in array are not unique. Let’s see the complete example,
