whats my cod problem?
//in the name of allah
#include<stdio.h>
int main()
{
int x=2, y=2, z;
int i,n;
scanf("%d\n", &n);
if (n == 1 || n == 2)
{
printf("%d\n", 2);
return 0;
}
for (i = 3; i<= n; i++){
z = x + y;
x = y;
y = z;
}
printf("%d\n", z);
return 0;
}
#include<iostream>
using namespace std;
int n, m;
int main()
{
cin>>n
cout<<n+1;
return 0;
}
try this Note: luka didn't receive AC. Solution looks ... weird. 1. It's better to help if author shows error (WA/TLE/etc) and test number.
2. int isn't enough. Try to use 64-bit variables. the problem is that when the input number comes to 45, even data type long long int cannot hold as big a result as 2269806340;(the result for 45), not to mention type int. long long is enough, 2269806340 is about 2^31-32, long long is 2^64, so it is double in the number of digits |
