Consider the following algorithm, where the array A is indexed 1 through n:
int add_them ( int n , int A[ ] ) {
index i , j , k ;
j = 0 ;
for ( i = 1 ; i <= n ; i++)
j = j + A[i] ;
k = 1 ;
for ( i = 1 ; i <= n ; i++)
k = k + k ;
return j + k ;
}
(a) If n = 5 and the array A contains 2, 5, 3, 7, and 8, what is returned?
(b) What is the time complexity T(n) of the algorithm?
