Method and system for number comparison during stream processing

A system for comparing a given number and a target number during stream processing, the system comprising:

• a processor and a memory communicably coupled thereto,
• wherein the memory is configured to store at least a preset state transition table to be executed by the processor,
• wherein the processor is configured to
• generate a current index associated with the given number based on a current digit pair including a first current digit from the given number and a second current digit from the target number, and a current state information associated with the given number;
• and
• look up the generated current index in a preset state transition table to identify a next state information, wherein the preset state transition table maintains a plurality of mappings, each of the mappings is between an index and a next state information;
• if the current digit pair includes a last digit of the given number or a last digit of the target number, determine a final comparison result based on the identified next state information;
• and
• if the current digit pair includes neither a last digit of the given number nor a last digit of the target number, take on the identified next state information as the current state information associated with the given number for comparison of a next digit pair.
