I post here the Levenberg-Marquardt algorithm for fitting sinus functions in C++ in low-level form, using only 1D arrays and for cycles. The sinusoidal function has form a*sin(x+b)+c, where a is the ...

Given an array nums. We define a running sum of an array as runningSum[i] = sum(nums[0]…nums[i]). Return the running sum of nums. Example 1: Input: nums = [1,2,3,4 ...

In this example, the numbers to be added together are already held in a 1D array of five integer values, so there is no need to request user input. If the user were to be asked to enter five ...
