Cumulative Totals
Daily sign-ups are stored in daily. Return an array of the same length where position i holds the total sign-ups from day 0 through day i inclusive.
Example 1
Input: daily = [4, 0, 3, 5] Output: [4, 4, 7, 12]
Example 2
Input: daily = [] Output: []
Constraints
- 0 <= daily.length <= 10^5
- -10^4 <= daily[i] <= 10^4
Hint 1
Carry a running sum as you walk the array.

Run checks your code on 2 sample tests. Submit runs all 6 tests, including hidden ones, and earns points. Use console.log to debug. Python's first run can take a few seconds while it starts.
