Cоnsider the fоllоwing function which determines whether or not а list contаins аny repeated values: def hasDup( data: list[int] ) -> bool:    for i in range( 0, len(data) ) :        for j in range( i + 1, len(data) ) :            if data[i] == data[j] :                return True    return False What is the big-Oh complexity of this algorithm, where n is the number of elements in data?
