Your development team has been assigned the task of designing a dynamic array generator tool to support software testing workflows. This generator service is designed to create an array that adheres to specific selection and unlocking rules.
The function takes the following parameters:
elements[n]: an array ofnpositive integers.availability: a string ofncharacters where:- Each character is either '0' or '1'.
- If
availability[i]= '1', the correspondingelements[i]is selectable. - If
availability[i]= '0', the correspondingelements[i]is initially locked.
To construct an output array, resultSet, the following process is executed exactly operations times. Initially, resultSet is empty.
- Choose any available element
elements[i], whereavailability[i]= '1'. Elements can be selected multiple times. - Append the chosen value to
resultSet. - For any
availability[i]= '0' whereavailability[i-1]= '1', updateavailability[i]to '1'. For instance, ifavailabilitywas '0100101' before selection, it would become '0110111' after selection.
The goal is to generate the lexicographically largest possible sequence resultSet after operations selections.
Note: A sequence x is considered lexicographically larger than sequence y if there exists an index i (0 β€ i < operations) where x[i] > y[i], and for any j (0 β€ j < i), x[j] = y[j].

elements = [10, 5, 7, 6] availability = "0101" operations = 2 return = [6, 7]
Step 1: Initially, only {6} is available since availability[3] = '1'.
Step 2: Select 6. This unlocks availability[2], making {7} available.
Step 3: Select 7. We have now performed operations = 2 selections.
elements = [4, 9, 1, 2, 10] availability = "10010" operations = 4 return = [4, 9, 10, 10]
Step 1: Initially available elements: {4, 10}.
Step 2: Select 4, unlocking availability[1] β {4} β {9}.
Step 3: Select 9, unlocking availability[2] β {9} β {1}.
Step 4: Select 10, unlocking availability[3] β {10} β {2}.
Step 5: Select 10 again.
arr = [5, 3, 4, 6] state = "1100" m = 5 return = [5, 5, 6, 6, 6]
