Light Rail. After all, during the day, the sports meet for a day and our physical strength is exhausted. At this timeEddieSaid to me, take out your telescope and see where there is a car. Right, I immediately took it out and searched for it on the road. "There is a public car in front, and someone gets off the bus. It's driving." Haha, it was a coincidence that we immediately rushed up and finally went home. We all said this when we got on the bus. It's already fast to lie down at home.2I

Given the sequence of KK integers {n_1n 1, n_2n 2, ..., n_kn K}, continuous sub columns are defined as {n_in I, n_{i+1}n i+1, ..., N_jn J}, where 1 \le i \le j \ Le k1≤i≤j≤k. Maximum sub columns and is defined as the largest of all contiguous child column elements. For example, given the sequence {-2, 11,-4, 13,-5,-2}, its contiguous sub columns {11,-4, 13} have the largest and 20. You are asked to write a

the seniority of N-N employees in a given company requires that the number of employees in each seniority segment be output by seniority. Input format:The input first gives a positive integerNn ( \le 10^5≤10?5?? ), that is, the total number of employees; then give nn integers, that is, the seniority of each employee, in the range of [0, 50]. Output format:The number of employees per seniority is output in

Enter an integer (no more than 9 digits) to represent a renminbi value (in yuan), please convert the uppercase Chinese format to the financial requirements. such as 23108 Yuan, converted into a "Wan Baize ba" Yuan. In order to simplify the output, the lowercase English letter a-j order represents the capital number 0-9, with S, B, Q, W, y respectively represents pick, hundred, thousand, million, billion. So 23108 yuan should be converted to output as "Cwdqbbai" Yuan.Input format:The input gives

A program is required to calculate the average of n rational numbers.Input format:Enter the first line to give the positive integer n (≤100), the second line in a1/b1 a2/b2 … the format given n fractional form of the rational number, where the numerator and denominator are all integers in the shaping range, if negative, the negative sign must appear at the front. Output format:The a/b average of n rational numbers is output in the format of a row. Note must be the simplest fractional form of the
