Your project team needs to work closely with a group of software testers. They have requested that your team create an array generator service to assist with testing software functionality. Create an array generator service.
Its input parameters are:
arr[n]containsnpositive integers.stateis a string that containsncharacters. Each character is a'0'or'1'. Ifstate[i] = '1',arr[i]is available. Ifstate[i] = '0',arr[i]is blocked.
To create an integer array, S, the following operation is performed exactly m times. S is initially empty.
- Choose any
arr[i]that is available, that is, wherestate[i] = '1'. The same element can be chosen any number of times. - Append the value in
arr[i]toS. - For all
state[i] = '0'such thatstate[i-1] = '1', changestate[i]to'1'. For example, ifstate = '0100101'before the operation, it equals'0110111'after the operation.
Find the lexicographically largest sequence S that can be obtained after m operations.
Note: A sequence x of length m is lexicographically larger than sequence y of length m if there exists such i (0 ≤ i < m), that x[i] > y[i], and for any j (0 ≤ 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] → {4} → {9}.
Step 3: Select 9, unlocking availability[2] → {9} → {1}.
Step 4: Select 10, unlocking availability[3] → {10} → {2}.
Step 5: Select 10 again.
arr = [5, 3, 4, 6] state = "1100" m = 5 return = [5, 5, 6, 6, 6]
arrhas lengthnand contains positive integers.stateis a string ofncharacters, each being'0'or'1'.- The selection operation is performed exactly
mtimes.
