同样的两种解法(～￣▽￣)～

1.python代码：

a = input().split()
maxx = ''
maxs = 0
for i in a:
    if len(i) > maxs:
        maxs = len(i)
        maxx = i
print(maxx)

2.c++代码

#include <bits/stdc++.h>
using namespace std;
int maxs;
int main()
{
    string a , maxx;
    while(cin >> a)
    {
        if (a.length() > maxs)
        {
            maxs = a.length();
            maxx = a;
        }
    }
    cout << maxx;
    return 0;
}

第一篇题解😄

#include <bits/stdc++.h>
using namespace std;
string s,a;
int n,ans=0;
int main()
{
    while(cin>>s)
    {
        if(s.length()>ans)
        {
            ans=s.length();
            a=s;
        }
        n++;
    }
    cout<<a;
    return 0;
}
