If we have an array of Interger values, find out a sub array
which has a maximum value of the array and start and end
positions of the array..The sub array must be contiguious.
Take the start add to be 4000.
For Ex if we have an array arr[] =
{-1,-2,-5,9,4,3,-6,8,7,6,5,-3}
here the sub array of max would be
{8,7,6,5} coz the sum of max contiguous array is 8+7+6+5 =
26.The start and end position is 4014(8) and 4020(5).

Hi All,
I hope the code which i have written ll give the exact
answer
Note: Compiler used is visual Studio 2005
Eg: if the the no of elemet is 12 and the elements are -1,-
2,5,6,-4,7,8,9,-3,10,20,-4 then output(sub array) should
contain the elements 10
and 20.
#include<stdio.h>
#include<conio.h>
int MakeSubArray(int *ptr, int size);
main()
{
int array[100];
int subarray[10], Index, no, j, k;
printf("ENTER NO OF ELEMENTS IN THE MAIN ARRAY \n");
scanf("%d", &no);
printf("\nENTER THE ELEMENTS\n");
for(j = 0; j<no; j++)
{
scanf("%d", &array[j]);
}
Index = MakeSubArray(&array[0],no);
printf("\nSTART POSITION\n%d", &array[Index]);
printf("\n\nSUB ARRAY ELEMENT(S) \n");
for(j = Index, k = 0; (array[j] >= 0) && (j < no);
j++, k++)
{
subarray[k] = array[j];
printf("%d ", subarray[k]);
}
printf("\n\nEND POSITION\n%d", &array[j-1]);
getch();
}
int MakeSubArray(int *ptr, int size)
{
int i, flag = 0, sum = 0, sum1 = 0, index = 0,
index1;
if(ptr != '\0' && size > 0)
{
for(i = 0; i <size; i++)
{
if(ptr[i] >= 0)
{
if(flag == 0)
{
index = i;
}
sum = sum + ptr[i];
flag++;
}
else
{
if(flag > 0 && sum1 < sum)
{
index1 = index;
sum1 = sum;
}
sum = 0;
flag = 0;
}
}
/*If the last element is non zero and it is part of
sub array then this condition is useful*/
if(flag > 0 && sum1 < sum)
{
index1 = index;
}
}
return index1;
}
