Basic running total
Input
compute_running_total([1, 2, 3])
Output
[1, 3, 6]
The running totals are 1, 1+2=3, 1+2+3=6.

Problem statement
Given a list of integers nums, compute the running total list where the i-th element of the result is the sum of nums[0] through nums[i]. Use loops to iterate the input list and accumulate the sum incrementally.
Task
Given a list of numbers, return a new list where each element is the running total up to that index.
Examples
Input format
A single function call compute_running_total(nums) where nums is a list of integers.
Output format
Return a list of integers representing the running totals.
Constraints
0 <= len(nums) <= 10000. Each number fits in Python's integer type.
Samples
Sample 1
Input
compute_running_total([5, -2, 7])
Output
[5, 3, 10]
Running totals: 5, 5+(-2)=3, 3+7=10.
