Codeforces Round #438 (Div. 1 + Div. 2 combined) 总结
来源:互联网 发布:淘宝网天猫女装棉衣 编辑:程序博客网 时间:2024/06/03 19:28
今天这波真是爆炸..比赛时写完4道,结果fst3道题……
结果只有rank1400+,从1896直接掉到1789。
(曾经,我离紫名是多么近;现在,我离紫名是多么遥远QAQ)….
我写完ABCD,结果fst了ABD..
A题我zz地在用char数组存字符串的时候用了==进行判断是否相等(想必是string类用多了qwq)..然后就GG了。
B题分类讨论的时候没考虑完全所有情况……直接fst(后来订正的时候还WA了几发)…
D题明知道直接存整个string会MLE,结果还是没改过来…结果当然是MLE啦..
C题以为自己的算法有小错误,结果重新改了一发交上去,少了300+分..(最气的是我在比赛结束后交了一发我第一次的代码,没想到A了……)
经过今天这次比赛……我知道了..在比赛的时候我们应该多检查检查自己的代码是否有错..然后多造几组数据对自己进行hack,要确保自己的代码不会出错..
