9 0 6 7 3 4 2 0 Let's say we want to search for 2 in the array So, we first sort the array The array after sorting is : 0 1 2 3 4 5 6 7 8 9 Now, we do the binary search Element found in the array Now, say we want to search for 10 Element not found in the ...

standard sequence containers (array,vectoranddeque), lists perform generally better in inserting, extracting and moving elements in any position within the container for which an iterator has already been obtained, and therefore also in algorithms that make intensive use of these, like sorting ...
