Resource Allocation Under Memory Constraints

HardPython

Problem

Implement a custom data structure or algorithm to solve a specific resource-allocation problem under tight memory constraints.

Use a single bitset-style representation to manage capacity contiguous resource slots. Implement allocation using first-fit placement and support releasing previously allocated ranges.

Contract

Implement def allocate_resources(capacity, operations):. Each operation is ['allocate', size] or ['release', start, size]. Return the starting index for every allocation, or -1 when no contiguous block is available. Release operations produce no output.

Constraints

  • 1 <= capacity <= 1000000
  • 1 <= len(operations) <= 500
  • 1 <= size <= capacity
  • Allocation operations have the form ['allocate', size].
  • Release operations have the form ['release', start, size].
  • Every release describes a valid allocated range.
  • Allocation uses the lowest possible starting index.

Function Signature

def allocate_resources(capacity, operations):
