- How to Compile the code
  1. Ensure having CUDA installed on the system
  2. To compile the program, run: make


- How to run the code
  - After compiling, run the program with the following command:  
    ./main <mode> <text_filename> <pattern_filename> <blockSize>

  - Commend-line arguments
    1. <mode>: 
       - 0: Run the parallel implementation (PTrie library) on the GPU
       - 1: Run the sequential implementation on the CPU
    2. <text_filename>: 
       - Path the the file containing the DNA text sequence
       - Example: DNA_text_100000000.txt
    3. <pattern_filename>:
       - Path to the file containing DNA patterns to search for
       - Example: Patterns_3bp_10.txt
    4. <blockSize>:
       - Only for parallel mode; this value does not affect the sequential code (mode 0)
       - The size of each CUDA block, which determines GPU thread grouping
       - Example: 256
