四、FORMAT STRINGS IN PYTHON 在现代编程语言如Python中,"f"字符在字符串前用来表示格式化字符串(f-strings)。自Python 3.6引入后,f-strings提供了一种新的字符串格式化方法,使得将变量的值嵌入字符串变得更加简洁和直观。你只需在字符串前加上"f",在字符串内的花括号中直接写入代码,代码的执行结果将被直接插入...
cf914F. Substrings in a String(bitset 字符串匹配) 题意 题目链接 Sol Orz jry 和上一个题一个思路吧,直接bitset乱搞,不同的是这次有了修改操作 因为每次修改只会改两个位置,直接暴力改就好了 代码语言:javascript 复制 #include<bits/stdc++.h>using namespace std;constintMAXN=1e5+10;char s[MAXN]...
[CF914F] Substrings in a String 题解 你谷link CF link 3000 分的题,正解似乎是什么分块套后缀自动机之类的,根本不会,但是我们有别的解法。 看到标签里有个 bitmask,于是恍然大悟,字符串题有位运算提示就很明显了,就是直接bitset乱搞字符串匹配。
