Input: The starting four elements of a sequence that follows the pattern: a, (ar + d), (ar? + d), (ar3 + d),... o Format: Four numbers each separated by space. Terminated by . Goal: Find integers a, r, and d with a 70 and r +0 that satisfy the input pattern. Output: Print the values of a, r, and d, each separated by a space. Terminate the line with a In. Example: Input: 15711 In o Output: 1 2 3 Remark: Every line of the input forms an input instance. Process each input instance as it is received. Stop at EOF. See public test cases for more examples
