Răspuns:
minimul pe coloana e aflat cred altfel decat in enunt... dar cred eficient
Explicație:
#include <iostream>
#include <fstream>
using namespace std;
ifstream f("var31.in");
ofstream g("var31.out");
int n,m,i,j,num,col[100];
void minim(int num, int &k)
{
if (num<k) k=num;
}
int maxim(int m, int col[])
{
int x=col[1];
for (int j=2; j<=m; ++j)
x=max(x,col[j]);
return x;
}
int main()
{
f >> n >> m;
for (j=1; j<=m; ++j)
f >> col[j];
for (i=2; i<=n; ++i)
{
for (j=1; j<=m; ++j)
{
f >> num;
minim(num,col[j]);
}
}
g << maxim(m,col);
}
