不知多少天前，我立下flag说要发高精加源码。今天，它来了！#include<bits/stdc++.h>using namespace std;string s1,s2;int a[10001],b[10001],c[10001];int main(){ cin>>s1; cin>>s2; int l1=s1.length(); int l2=s2.length(); for(int i=0; i<l1; i++) { a[l1-i]=int(s1[i]-48); } for(int i=0; i<l2; i++) { b[l2-i]=int(s2[i]-48); } int l3=1; int t=0; while(l3<=l1||l3<=l2) { c[l3]+=a[l3]+b[l3]+t; t=c[l3]/10; c[l3]%=10; l3++; } c[l3]=t; if(c[l3]==0) l3--; for(int i=l3; i>0; i--) cout<<c[i]; return 0;}
