the N series, and when I say a little bit, I mean only a little bit. The problem reads How ever much I like paper, rock and scissor we only use paper and scissor in the problem Welcome to the Shire… Well at least welcome to Middle Earth, we don’t actually need to travel through the shire in the next > Gandalf is travelling from ROHAN to RIVENDELL to meet Frodo but > there is no direct route from ROHAN (T1) to RIVENDELL (Tn). > But there are towns T2,T3,T4…Tn-1 such that there are N1 routes > from Town T1 to T2, and in general, Ni routes from Ti to > Ti+1 for i=1 to n-1 and 0 routes for any other Ti to Tj for j ≠ > i+1 > Find the total number of routes Gandalf can take to reach Rivendell > from Rohan. > Gandalf has to pas* all the towns Ti for i=1 to n-1 in numerical > order to reach Tn. > For each Ti , Ti+1 there are only Ni distinct routes Gandalf can > take. > The first line contains an integer T, T test-cases follow. > Each test-case has 2 lines. The first line contains an integer N > (the number of towns). > The second line contains N – 1 space separated integers where the > ith integer denotes the number of routes, Ni, from the town Ti to > Ti+1 There are two things we need to get our heads around. There is the first part which is how many paths there are, and then there is the The former problem of the paths is rather simple as it is a simple combinatorics problem and the total number of paths are just the The problem of the modulo operator can be treated in different ways. Since we are using Python as implementation language we can completely ignore it, as it can handle arbitrarily large integers. However, we can also solve it as we have done for Project Euler problem 48. Which means that for every time we multiply with the next set of paths we can also take the modulo, which means we will keep the total size
