To find the weight of a string "s" and "w" modulo 3914, you would typically need to define what "weight" means in this context (e.g., the sum of ASCII values, character counts, etc.). Once you have that defined, you would calculate the weight for both strings and then take the result modulo 3914. Without specific definitions for "weight," it's impossible to provide a numerical answer.
