/*prints subarray producing maximum sum.Efficiency is O(n)*/
#include <iostream.h>
#include<conio.h>
main()
{
int n,i,c=0,sum=0,max=0,a[25],s=-1,e=-1;
cout<<"enter n:";
cin>>n;
cout<<"enter elements:";
for(i=1;i<=n;i++)
cin>>a[i];
for(i=1;i<=n;i++)
{
if(a[i]+sum>0)
{
sum+=a[i];
if(sum>=max)
s=i-c;
c++;
}
else
{
sum=0;
c=0;
}
if(sum>max)
{
max=sum;
e=i;
}
}
cout<<"max sum is:"<<max;
cout<<"\n\nmax sum producing sub array is:";
if(s!=-1&&e!=-1)
for(i=s;i<=e;i++)
cout<<"\t"<<a[i];
getch();
return 0;
}

I need your help, i need a Turbo C code for this problem.. hope u'll help me guys.? Your program will have a 3x3 array. The user will input the sum of each row and each column. Then the user will input 3 values and store them anywhere, or any location or index, temporarily in the array. Your program will supply the remaining six (6) values and determine the exact location of each value in the array. Example: Input: Sum of row 1: 6 Sum of row 2: 15 Sum of row 3: 24 Sum of column 1: 12 Sum of column 2: 15 Sum of column 3: 18 Value 1: 3 Value 2: 5 Value 3: 6 Output: Sum of Row 1 2 3 6 4 5 6 15 7 8 9 24 Sum of Column 12 15 18 Note: Your program will not necessary sort the walues in the array Thanks..

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
