Integer numElements is read from input and integer array userRating is declared with size numElements. Then, numElements integers are read from input and stored into userRating. Replace the middle element in userRating with $-1.$

Ex: If the input is:

$5$

$2539109742$

then the output is:

Updated ratings: $2539-19742$

Note: The index of the middle element is found by dividing the array's length by $2.$
