working with null elements in an array

i have an array (with each element length "n") which is dynamic and has alphanumeric characters.

i want to check if any of the elements of the array are null and replace it with a string of "n" zeros for that element.

can you suggest me a code for the same.

Code:
STR=""
for ((N=0; N<${#ARRAY[@]}; N++))
do
        [ -z "${ARRAY[$N]}" ] || continue
        ARRAY[$N]="$STR"
        STR="${STR}0"
done
