Question 22523: Shift the Full State and Append Each Exact New Scalar

Original question and givens

Use order r=3, coefficients=[1, 2, 3] in oldest-to-newest order, constant=0 and initial_values=[22, 23, 24], where initial_values[j]=a_j. For n≥r, a_n=constant+sum over j=0..r−1 of coefficients[j]*a_(n−r+j). The state shifts left then appends the new scalar. All intermediate integer operations must be safe. Target index=8. Give (order, initial_values, target_n, prefix, target_value, certificate).
