"""# ### 谜题描述 Mahmoud has an array a consisting of n integers. He asked Ehab to find another array b of the same length such that: * b is lexicographically greater than or equal to a. * bi ≥ 2. * b is pairwise coprime: for every 1 ≤ i < j ≤ n, bi and bj are coprime, i. e. GCD(bi, bj) = 1, where GCD(w, z) is the greatest common divisor of w and z. Ehab wants to choose a special array so he wants the lexicographically minimal array between all the variants. Can you find it? An array x is lexicographically greater than an array y if there exists an index i such than xi > yi and xj = yj for all 1 ≤ j < i. An array x is equal to an array y if xi = yi for all 1 ≤ i ≤ n. Input The first line contains an integer n (1 ≤ n ≤ 105), the number of elements in a and b. The second line contains n integers a1, a2, ..., an (2 ≤ ai ≤ 105), the elements of a. Output Output n space-separated integers, the i-th of them representing bi. Examples Input 5 2 3 5 4 13 Output 2 3 5 7 11 Input 3 10 3 7 Output 10 3 7 Note Note that in the second sample, the array is already pairwise coprime so we printed it. Here is a reference code to solve this task. You can use this to help you genereate cases or validate the solution. ```python MAX_NUM = 2000000 prime_str = ('2 3 5 7 11 13 17 19 23 29 ' + '31 37 41 43 47 53 59 61 67 71 ' + '73 79 83 89 97 101 103 107 109 113 ' + '127 131 137 139 149 151 157 163 167 173 ' + '179 181 191 193 197 199 211 223 227 229 ' + '233 239 241 251 257 263 269 271 277 281 ' + '283 293 307 311 313 317 ' ) prime_list = [int(p) for p in prime_str.split()] used = [False] * MAX_NUM n = input() a = list(map(int,raw_input().split())) def record(x): t = [] for p in prime_list: if x % p == 0: while x % p == 0: x = x // p t.append(p) if x == 1: break if x != 1: t.append(x) for ti in t: for i in range(ti, MAX_NUM, ti): used[i] = True b = [] for ai in a: if not used[ai]: b.append(ai) record(ai) else: temp = ai + 1 while used[temp]: temp += 1 b.append(temp) record(temp) break temp = 2 while len(b) < len(a): while used[temp]: temp += 1 b.append(temp) record(temp) print(' '.join(str(x) for x in b)) ``` 请完成上述谜题的训练场环境类实现,包括所有必要的方法。 """ from bootcamp import Basebootcamp import random from bootcamp import Basebootcamp class Dmahmoudandehabandanotherarrayconstructiontaskbootcamp(Basebootcamp): def __init__(self, max_n=10, max_ai=100): self.max_n = max_n self.max_ai = max_ai @staticmethod def generate_b(a): MAX_NUM = 2000000 prime_str = ('2 3 5 7 11 13 17 19 23 29 ' '31 37 41 43 47 53 59 61 67 71 ' '73 79 83 89 97 101 103 107 109 113 ' '127 131 137 139 149 151 157 163 167 173 ' '179 181 191 193 197 199 211 223 227 229 ' '233 239 241 251 257 263 269 271 277 281 ' '283 293 307 311 313 317') prime_list = [int(p) for p in prime_str.split()] used = [False] * (MAX_NUM + 1) n = len(a) b = [] def record(x): t = [] tmp_x = x for p in prime_list: if tmp_x % p == 0: while tmp_x % p == 0: tmp_x = tmp_x // p t.append(p) if tmp_x == 1: break if tmp_x != 1: t.append(tmp_x) for ti in t: if ti > MAX_NUM: continue for i in range(ti, MAX_NUM + 1, ti): used[i] = True for ai in a: if ai <= MAX_NUM and not used[ai]: b.append(ai) record(ai) else: temp = ai + 1 while temp <= MAX_NUM and used[temp]: temp += 1 if temp > MAX_NUM: temp = ai + 1 b.append(temp) record(temp) break # Break after first replacement temp = 2 while len(b) < len(a): while temp <= MAX_NUM and used[temp]: temp += 1 if temp > MAX_NUM: break b.append(temp) record(temp) temp += 1 return b def case_generator(self): n = random.randint(1, self.max_n) a = [random.randint(2, self.max_ai) for _ in range(n)] expected_b = self.generate_b(a) return { 'n': n, 'a': a, 'expected_b': expected_b } @staticmethod def prompt_func(question_case): a_str = ' '.join(map(str, question_case['a'])) return ( f"You are given an array a of {question_case['n']} integers.
