@ mohit my first post on here. this solution got ac in spoj
main()
{
unsigned int n,m,sum,max,i,j;
sum=0;max=1;
n=in.ReadNextUInt();
m=in.ReadNextUInt();
unsigned int *a = new unsigned int[n];
unsigned int *p = a;
for (i=0; i < n; i++)
*(p++) = in.ReadNextUInt();
i=0;
j=0;
while(j<n)
{
sum+=a[j++];
while(sum>m)
{
sum-=a[i++];
}
if(sum>max)
max=sum;
}
out.WriteUInt(max,'\n');
out.Flush();
return 0;
}
