Code Help reading the array and sum of the array elements
Hi All,

need help with reading the array and sum of the array elements.
given an array of integers of size N . You need to print the sum of the elements in the array, keeping in mind that some of those integers may be quite large.

Input Format

The first line of the input consists of an integer N . The next line contains space-separated integers contained in the array.

Output Format

Print a single value equal to the sum of the elements in the array.
Code:
1<=N<=10
0<=A[i]<=10000000000
5
1000000001 1000000002 1000000003 1000000004 1000000005

Output
Code:
5000000015

what I have done so far:

code:

Code:
#input array size
read N
while [ $N -ge 1 -a $N -le 10 ]
do
echo $N
break
done
for i in `seq 0 N-1`;
do 
read -a array[i]
if[ "${array[i]}" -ge 0 -a "${array[i]}" -le 10000000000 ]; then
echo "${array[i]}"
fi
done
#sum=expr `sum + ${ array[i] }`

Could you please let me know where I went wrong?

slangt.f(3)							      LAPACK							       slangt.f(3)

NAME

       slangt.f -

SYNOPSIS

   Functions/Subroutines
       REAL function slangt (NORM, N, DL, D, DU)
	   SLANGT

Function/Subroutine Documentation
   REAL function slangt (characterNORM, integerN, real, dimension( * )DL, real, dimension( * )D, real, dimension( * )DU)
       SLANGT

       Purpose:

	    SLANGT  returns the value of the one norm,	or the Frobenius norm, or
	    the  infinity norm,  or the  element of  largest absolute value  of a
	    real tridiagonal matrix A.

       Returns:
	   SLANGT

	       SLANGT = ( max(abs(A(i,j))), NORM = 'M' or 'm'
			(
			( norm1(A),	    NORM = '1', 'O' or 'o'
			(
			( normI(A),	    NORM = 'I' or 'i'
			(
			( normF(A),	    NORM = 'F', 'f', 'E' or 'e'

	    where  norm1  denotes the  one norm of a matrix (maximum column sum),
	    normI  denotes the	infinity norm  of a matrix  (maximum row sum) and
	    normF  denotes the	Frobenius norm of a matrix (square root of sum of
	    squares).  Note that  max(abs(A(i,j)))  is not a consistent matrix norm.

       Parameters:
	   NORM

		     NORM is CHARACTER*1
		     Specifies the value to be returned in SLANGT as described
		     above.

	   N

		     N is INTEGER
		     The order of the matrix A.  N >= 0.  When N = 0, SLANGT is
		     set to zero.

	   DL

		     DL is REAL array, dimension (N-1)
		     The (n-1) sub-diagonal elements of A.

	   D

		     D is REAL array, dimension (N)
		     The diagonal elements of A.

	   DU

		     DU is REAL array, dimension (N-1)
		     The (n-1) super-diagonal elements of A.
