Input: set = [10 20 30 70 80 90 100 40 50 60], valueOfElementToBeDeleted = 100 Output: 10 20 30 40 50 60 70 80 90 Input: set = [1 2 3 4 5], valueOfElementToBeDeleted = 3 Output: 1 2 4 5
Sets are a type of associative containers in which each element has to be unique because the value of the element identifies it. The value of the element cannot be modified once it is added to the set, though it is possible to remove and add the modified value of that element.
Approach: In this method, the last element is deleted by using the erase function and calling it with the value of the last element as its argument. If the value of the last element is not known, then use the previous method.
size_type erase (const value_type& valueOfElementToBeDeleted);
Below is the implementation of the above approach:
Set originally: 10 20 30 40 50 60 70 80 90 Set after deleting 50: 10 20 30 40 60 70 80 90
