Find out maximim sum of sub Array
example
array={2,3,-1,4,9}
maximum sum of sub array=17

• #include
  #include
  int maxSubArraySum(int a[], int size)
  {
  int max_so_far = 0, max_ending_here = 0;
  int i;
  for(i = 0; i < size; i++)
  {
  max_ending_here = max_ending_here + a[i];
  if(max_ending_here < 0)
  max_ending_here = 0;
  if(max_so_far < max_ending_here)
  max_so_far = max_ending_here;
  }
  return max_so_far;
  }
  
  /*Driver program to test maxSubArraySum*/
  int main()
  {
  int a[] = {2,3,-1,4,9};
  int n = sizeof(a)/sizeof(a[0]);
  int max_sum = maxSubArraySum(a, n);
  printf("Maximum contiguous sum is %dn", max_sum);
  getchar();
  return 0;
  }

• an array should not equal to sub array so sub array can be formed as
  B={2,3,-1,4}=2-1+3+4=8
  B={3,-1,4,9}=3-1+4+9=15 similarly the maximum sum of sub array will be
  B={3,4,2,9}=18

• The question is vague.
