Z3创建两个具有相同元素但顺序不同的intVectors

from z3 import *

# 创建Z3上下文
ctx = Context()

# 定义变量
v1 = Array('v1', IntSort(), IntSort())
v2 = Array('v2', IntSort(), IntSort())

# 添加约束条件：v1和v2的长度相同
length_constraint = Length(v1) == Length(v2)

# 添加约束条件：v1和v2的元素相同
element_constraint = ForAll([i], Implies(And(i >= 0, i < Length(v1)), Select(v1, i) == Select(v2, i)))

# 添加约束条件：v1和v2的顺序不同
order_constraint = Not(ForAll([i, j], Implies(And(i >= 0, i < Length(v1), j >= 0, j < Length(v1), i < j), Select(v1, i) == Select(v2, j))))

# 添加所有约束条件
constraints = And(length_constraint, element_constraint, order_constraint)

# 创建求解器
solver = Solver(ctx)

# 添加约束条件到求解器
solver.add(constraints)

# 检查是否存在解
if solver.check() == sat:
    # 获取解
    model = solver.model()
    v1_solution = [model.evaluate(Select(v1, i)).as_long() for i in range(model.evaluate(Length(v1)).as_long())]

    print("v1_solution:", v1_solution)
    print("v2_solution:", v2_solution)
else:
    print("No solution found.")
