Tanya and Password (Fleury algorithm)Topic Links:Http://codeforces.ru/problemset/problem/508/DTest instructionsGive n a string of length 3, such as: ABC bca AAB if the suffix of a string is 2 and the length of the other string is a prefix of 2, then the two strings can be connected, for example: AABCA, and then the N strings can form a graph, and a Oraton path on the graph is obtained.Limi

Test instructions: Morse code, enter a number of letters of the Morse number, a dictionary and several encodings. For each number, determine which word it might be,If more than one word matches exactly, output the first word and add a "! "; If you can't match exactly, add or remove as few characters as possible at the end of the code,Make it match a word and add "? ”。Analysis: The first time to do, a look at what ah, do not, now come back to see, found can be done, you can use the map of the STL

Topic descriptionGiven a sequence of size n (nExercisesThe number of n as a binary, if the number of n is required and equal to the number of N or value, then for each bit of n number, there may be a maximum of 1, because more than one will produce a carry.Because number I if the current bit is placed 0, but the current bit of r[i] is 1, then the position can be placed at will, there is no limit, so we can use dp[i][j] to indicate in the first bit, the current state is J of the number of conform

NYOJ 508 remainder summation (number theory problem) Description Give you two numbers n, k, the requested value. Input two numbers n, k (1 5 45 3Sample output 57 Question Analysis: This question cannot be directly violent. It has a large value and can only use the sqrt (n) algorithm to calculate the remainder sum of n % I, I = 1 ~ N; Note: n % I = n/I * I; Therefore, we can simulate ~ Sqrt (n); sum + = n % I; for j = n/I correspondi
