When you have this type problem "correct answer on my system but a wrong answer when I submit" use the Codechef ide to find the problem :) – Anupam Ghosh Nov 12 '15 at 12:23 add a comment | 1 Answer 1 Hence, the branching factor is at most D = B*M. Since the depth of the recursion tree is at most 2, hence the time complexity is upper-bounded by D^2, which is quite less. I write essays on various engineering topics and share it through my weekly newsletter I was unable to find where it failed. For example: T1: 1-10 -10 -9 9 -7 9 Your Output = 2, Actual answer = 3.

If you like what you read subscribe to my newsletter. First, let us notice that we can always make the initial triplet equal to the final triplet in at most 3 moves, by individually adding the difference between each a_i and b_i. We need to convert our list of ints to a tuple of ints (as a list is not hashable, but a tuple is) t = tuple (input_list) print the result; print hash (t) Other Optimizations (Not necessary for credit here): If the first input line == '0' then bail, there isn't anything interesting to parse; Call strip() on the input to remove trailing and leading whitespace. contests.

The number of possible operations is B = 3+3+3=9, and the number of subsets possible is M=2^3-1. TTUPLE - Editorial. Questions solved from Various Coding websites viz. a = [2,3,4] Then compute and print the result of . This implies that the maximum multiplication required anywhere should be at max 10 and similarly maximum sum required should be 20…so i ran the brute for every possible sum & multiplication but this failed…it however worked for 100 and 200 respectively…why? Case #3 - is actually my solution based on itertools.groupby, itertools.islice features and simple arithmetic trick of 2 steps to sum up maximals (items with greater number of occurrences of 1 or 0 flags) of each group within a trainset: Leverage CodeChef’s expertise to engage and upskill your teams via programming contests and other high-quality learning resources. blank_kami June 19, 2020, 1:14pm #170. 0 does lists and tuples in python ends with null('/0') charc like in C?
