Write a program to complete the following command: new id - create a specified sequence of Numbers for id (id < 200000) Add id num - to join the sequence of Numbers for id integer num merge id1 id2 - merger sequence number of id1 and id2, and make id2 empty unique id - remove repetitive element in the sequence id out id - from small to large, output the elements of sequence of Numbers for ids separated by Spaces

Sure! Here is a Python program that can perform the operations you described:

from collections import OrderedDict

class NumberSequence:
    def __init__(self):
        self.sequences = {}
        
    def new(self, id):
        if id >= 200000:
            return "Error: id must be less than 200000"
        
        self.sequences[id] = []
        return "Success: created sequence for id {}".format(id)
    
    def add(self, id, num):
        if id not in self.sequences:
            return "Error: sequence for id {} does not exist".format(id)
        
        self.sequences[id].append(num)
        return "Success: added {} to sequence for id {}".format(num, id)
    
    def merge(self, id1, id2):
        if id1 not in self.sequences:
            return "Error: sequence for id {} does not exist".format(id1)
        if id2 not in self.sequences:
            return "Error: sequence for id {} does not exist".format(id2)
        
        merged_sequence = self.sequences[id1] + self.sequences[id2]
        self.sequences[id1] = merged_sequence
        self.sequences[id2] = []
        return "Success: merged sequence for id {} and id {}, and emptied id {}".format(id1, id2, id2)
    
    def unique(self, id):
        if id not in self.sequences:
            return "Error: sequence for id {} does not exist".format(id)
        
        unique_sequence = list(OrderedDict.fromkeys(self.sequences[id]))
        self.sequences[id] = unique_sequence
        return "Success: removed duplicate elements from sequence for id {}".format(id)
    
    def out(self, id):
        if id not in self.sequences:
            return "Error: sequence for id {} does not exist".format(id)
        
        sorted_sequence = sorted(self.sequences[id])
        output_str = " ".join(str(num) for num in sorted_sequence)
        return output_str

To use this program, you can create a `NumberSequence` object and call its methods to perform the desired operations. For example:

ns = NumberSequence()

print(ns.new(1))    # Success: created sequence for id 1
print(ns.add(1, 5)) # Success: added 5 to sequence for id 1
print(ns.add(1, 3)) # Success: added 3 to sequence for id 1
print(ns.add(2, 7)) # Error: sequence for id 2 does not exist
print(ns.merge(1, 2)) # Error: sequence for id 2 does not exist
print(ns.new(2))    # Success: created sequence for id 2
print(ns.add(2, 7)) # Success: added 7 to sequence for id 2
print(ns.add(2, 3)) # Success: added 3 to sequence for id 2
print(ns.merge(1, 2)) # Success: merged sequence for id 1 and id 2, and emptied id 2
print(ns.out(1))    # 3 5 7
print(ns.unique(1)) # Success: removed duplicate elements from sequence for id 1
print(ns.out(1))    # 3 5 7
