Check if the array
nums
is empty or has only one element; if so, return
nums
as is.
Iterate over the array starting from the second element (index 1).
For each element at index
i
, update
nums[i]
by adding
nums[i-1]
to it.
Continue this process until the end of the array is reached.
Return the modified array
nums
, which now contains the running sums.
