Unsetting elements of array2 will create holes in the array, which means
${#arra...@]} will no longer be a useful way to iterate through the
whole array. (${#arra...@]} will become too small, as it counts the
number of elements, rather than naming the highest index and adding one.)
To iterate over a sparse array by index, you need to use ${!arra...@]}
(requires bash 3.0 or higher) which returns the list of indices. Try
replacing your while loop with:
for n in ${!arra...@]}
