# 测试示例
print(check_even_odd(4))  # 输出: (4, 'even')
print(check_even_odd(7))  # 输出: (7, 'odd')

print(check_range(50))   # 输出: (50, 'in range')
print(check_range(150))  # 输出: (150, 'out of range')

print(check_grade(95))   # 输出: (95, 'A')
print(check_grade(85))   # 输出: (85, 'B')
print(check_grade(75))   # 输出: (75, 'C')
