比较两个整数而不使用任何比较(递归、python)

def compare_integers(num1, num2):
    diff = num1 - num2
    if diff > 0:
        return "num1 > num2"
    elif diff < 0:
        return "num1 < num2"
    else:
        return "num1 = num2"

# 示例调用
print(compare_integers(10, 5))  # 输出：num1 > num2
print(compare_integers(5, 10))  # 输出：num1 < num2
print(compare_integers(7, 7))   # 输出：num1 = num2

def compare_integers(num1, num2):
    diff = num1 - num2
    sign = (diff >> 31) & 1  # 获取差值的符号位
    if sign == 1:
        return "num1 < num2"
    elif sign == 0:
        return "num1 > num2"
    else:
        return "num1 = num2"

# 示例调用
print(compare_integers(10, 5))  # 输出：num1 > num2
print(compare_integers(5, 10))  # 输出：num1 < num2
print(compare_integers(7, 7))   # 输出：num1 = num2
