We strongly recommend to minimize your browser and try this yourself first. The number of ways decoding "12" is 2. A message containing letters from A-Z is being encoded to numbers using the following mapping: 'A' -> 1 'B' -> 2 ... 'Z' -> 26 Given an encoded message containing digits, determine the total number of ways to decode it. Given numeric string str, the task is to count the number of ways the given string can be split, such that each segment is a prime number. N = 3 Output = 25 3 sections, which means possible ways for one side are BSS, BSB, SSS, SBS, SSB where B represents a building and S represents an empty space Total possible ways are 25, because a way to place on one side can correspond to any of 5 ways on other side.
