原题链接 题目大意:大数,20进制的加法计算. 解法:convert函数把字符串转换成数组,add函数把两个大数相加. 参考代码: #include<stdio.h> #include<string.h> char* Digit="0123456789abcdefghij"; void convert(char*,int*); void add(int*,int*,int*); void print(int*); int main(){ char str1[10…

一道简单题,简单的20进制加减法,我这里代码写的不够优美,还是可以有所改进,不过简单题懒得改了... #include <stdio.h> #include <string.h> int invert(char c) { ) ; else ; } char reinvert(int a) { ) ; else ; } char add(char a1,char a2,int *c) { int t1,t2,sum; t1=invert(a1); t2=invert(a2); sum…

此题不难,主要思路便是IDDFS(迭代加深搜索),关键在于优化. 一个IDDFS的简单介绍,没有了解的同学可以看看: https://www.cnblogs.com/MisakaMKT/articles/10767945.html 我们可以这么想,设当前规定长度为M,题目要求得出的数为N. 在搜索中,当前的步数为step,当前的数列为 数组a. 首先来确定思路,便是在以得出的数列a中枚举每两个数相加得出sum,然后继续搜索下一步. 初步的代码便是: void iddfs(int step) {…

原题 给出数n,求出1......n 一串数,其中每个数字分解的两个加数都在这个序列中(除了1,两个加数可以相同),要求这个序列最短. ++m,dfs得到即可.并且事实上不需要提前打好表,直接输出就可以. #include<cstdio> using namespace std; int dep=0,n; int a[102]; bool dfs(int step) { if(step>dep) return a[dep]==n; for(int i=0;i<step;i++) {…
