c++&python 题解 100%AC

c++:

#include <bits/stdc++.h>
using namespace std;
int a[10010],b[10010],c[10010];
int main(){
	string as,bs;
	cin>>as>>bs;
	reverse(as.begin(),as.end()),reverse(bs.begin(),bs.end());
	a[0]=as.size(),b[0]=bs.size(),c[0]=max(a[0],b[0]);;
	for(int i=0;i<as.length();i++)a[i+1]=as[i]-48;
	for(int i=0;i<bs.length();i++)b[i+1]=bs[i]-48;
	for(int i=1;i<=c[0];i++){
        c[i+1]=(a[i]+b[i]+c[i])/10;
		c[i]=(a[i]+b[i]+c[i])%10;
	}
	if(c[c[0]+1]==1)c[0]++;
	for(int i=c[0];i>=1;i--)cout<<c[i];
	return 0;
}

python:

a=input().strip()
b=input().strip()
a_l=list(a)
a_p=0
if(a[0]=='0' and a[1]=='0'):
    print('00',end='')
print(int(a)+int(b))
