# COME ON CODE ON

A blog about programming and more programming.

## Size Contest

Looks like i am having some affair with shorter codes. Anyways, there is this question on SPOJ. You have to write the shortest code for finding the sum of all positive integers,given a set of T integers followed by T.

As always i am far away from optimal result :

```#include"iostream"
int a,t,s;
main()
{
for(std::cin>>t;t--;std::cin>>a,s+=a>0?a:0);
std::cout<<s;
}
&#91;/sourcecode&#93;
And Python Solution :
&#91;sourcecode language='python'&#93;t=input()
s=0
while t:
x=input()
s+=x*(x>0)
t-=1
print s```

If you have a shorter C++ or Python code, help me out. Between try this line to see the path of your file.

`printf("The source file name is %s\n",__FILE__);`

1. in place of comparing a>0, you can just check the sign bit. That will be a lot more optimized 🙂

2. how? Remember the aim is to minimize the size…

3. # #include”iostream”
# int a,t,s;
# main()
# {
# for(std::cin>>t;t–;std::cin>>a,s+=(a>>31)?0:a);
# std::cout<<s;
# }

it won’t reduce size but obviously optimize the cose in same size.

PS: assumed 32 bit int.

4. #include
you can use this header file and remove std::

5. Correction in previous comment
#include”rope.h”
you can use this header file and remove std::

s+=a>0?a:0

u can write
s+=a>?0

7. A shorter python code… 42chars only
s=0
i=input
exec(“s+=max(0,i());”)*i()
print s
