C++ - List Part 4: Advanced List Operations

Lists offer several advanced methods for managing elements and optimizing storage.

Examples and Explanation

Merging Two Lists

std::list<int> list1 = {1, 3, 5};

std::list<int> list2 = {2, 4, 6};

list1.merge(list2); // Merges list2 into list1

Explanation: The merge() method combines two sorted lists into one.

Sorting a List

myList.sort(); // Sorts in ascending order

Explanation: Use the sort() method to sort elements. This is particularly useful as lists do not support random access.

Removing Duplicates

myList.unique();

Explanation: The unique() method removes consecutive duplicate elements.

Reversing a List

myList.reverse();

Explanation: The reverse() method reverses the order of elements in the list.
