Chart the Cumulative Revenue

Intermediate

A dashboard plots revenue accumulating day by day. Given the daily amounts, produce the running total at each point in the series.

Implement `solve(List<Integer> nums)` to return a list where each element is the cumulative sum up to and including that index.

Examples

Input[1, 2, 3, 4]

Output[1, 3, 6, 10]

Input[5, -2, 7]

Output[5, 3, 10]

Hints

Keep a running sum; append its current value at each step.

List<Integer> solve(List<Integer> nums) {
    // return cumulative sums
    return null;

Your code runs in a secure sandbox against multiple hidden test cases. The problem is solved only when every test passes. Each run is isolated and any data changes are rolled back automatically.
