for the following question I cant figured a solution need some help. (ARM simulator must be used)

Question:

Take the array program given above, and reserve space for a second array of the same size, labelled sum. Write a loop-initialising sum to the sum of all preceding elements of array.

In Java sum[i] = sum[i-1] + array[i] having initialised sum[0] to array[0].

You can confirm that you have correctly implemented this by outputting the final value, which should be 210 for an array of size 20.
