6. Write a python program to demonstrate First Fit- Memory Management Technique

class MemoryManager:
    def __init__(self, memory_size):
        self.memory_size = memory_size
        self.memory = [0] * memory_size
        self.processes = {}

    def allocate_first_fit(self, process_id, size):
        for i in range(self.memory_size - size + 1):
            if all(self.memory[i + j] == 0 for j in range(size)):
                for j in range(size):
                    self.memory[i + j] = process_id
                self.processes[process_id] = (i, size)
                return True
        return False

    
    def print_memory(self):
        print("Memory:")
        for i, val in enumerate(self.memory):
            print(val, end=" ")
            if (i + 1) % 20 == 0:
                print()
        print()

if __name__ == "__main__":
    memory_manager = MemoryManager(100)

    # First fit allocation
    print("First Fit Allocation:")
    memory_manager.allocate_first_fit("P1", 20)
    memory_manager.print_memory()

    

   
Output:
First Fit Allocation:
