• Day 1: The Tyranny of the Rocket Equation: Find the weight of fuel that is required to launch a rocket. Weight of each consequent module is input as a line and the cumulative answer is to be output as a single value to be print in main(). The logic to my solution is that since weight can't be negative and we seem to only consider integer values, we can utilise the u32 type as input and return variable of sum_of_fuel_required function on encountering a module weight as input by the user. The function is defined in the day_one module. A loop iterates on the modules as input and calculates the fuel requirement according to provided formula. A while iterates over fuel and offset until all weights, including that added by the fuel is taken into consideration.
