WebNov 19, 2024 · Ordered set is a policy based data structure in g++ that keeps the unique elements in sorted order. It performs all the operations as performed by the set data structure in STL in log (n) complexity and performs two additional operations also in log (n) complexity . order_of_key (k) : Number of items strictly smaller than k . 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.
