您好,经过您对题目的补充说明,以及对题目的重新推导之后,将会上传新的题解。如果我对该补充说明的理解无误的话(也就是碳含量一旦严格小于t%即为熟铁,意味着此次炼钢失败),则公式推导是无误的。感谢您对题目的补充说明以及对题解的贡献!

您好,您的理解无误。另外,钢的定义在题目中已经写明,不是碳含量小于等于t%,而是碳含量等于t%。虽然根据公式解出将生铁炼成钢需要负数时间显然不合理,不能作为答案,然而当碳含量小于t%的情况,根据不同的诠释方式(开放世界诠释与封闭世界诠释),确实认为是钢和不是钢都是合理的,即本题在解出炼钢时间<0时直接输出0也是一种合理的理解。本题原本的设计思路是将熟铁失败的情况隐藏在题目描述中,因表述不清造成的诸多麻烦特在此致歉。
