c++ question

Answer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.

- (Minimum and Maximum) We often want to find the minimum and maximum values in a vector as well as the indices at which these values occur. For this problem do not use the built in min or max function (or any other function which trivializes the problem). min_max Function: Input variables: • a vector representing the list of numbers; you may assume each value is unique Output variables: • a scalar representing the minimum value • a scalar representing the index where minimum value is located in the list • a scalar representing the maximum value • a scalar representing the index where maximum value is located in the list A possible sample case is: » [min_val, min_i, max_val, max_i] = min_max(1:5) min_val = 1 min_i max_val = max_i = 1 5 » [min_val, min_i, max_val, max_i] = min_max([2, 3, 7, 1, 4]) min_val = 1 min_i 4 max_val = max_i = 3 7 » [min_val, min_i, max_val, max_i] = LXX_QYY([1, 2, 3, 4, -1, 0]) min_val = -1 min_i max_val = %3D 4 max_i = 4
