👉 Upshifts are a type of data transformation that involves shifting values in a vector or array. In other words, they change the order of elements within an array. This can be done by adding one to each element and then moving them to the end of the array. For example, if we have an array `arr` with 3 elements, we can upshift it as follows: ``` upshift(arr) = arr[2] + arr[1] + arr[0]
