	    scanf("%d%d",&n,&q);
	    int f,d,i=0,floorCount=0,currentFloor=0;
	    for(i=0;i<q;i++){
	        scanf("%d%d",&f,&d);
	    
            floorCount+= abs(currentFloor-f) + abs(d-f);
	        currentFloor = d;

	        }
	    printf("%d\n",floorCount);
	}
	return 0;
}

Use long double data type for floorCount, as the sum goes above the int range
