Problem Description
Now give you two integers n m,you just tell me the m-th number after radix point in 1/n,for example n=4,the first numble after point is 2,the second is 5,and all 0 followed

Sum It Up
Given a specified total t and a list of n integers,find all distinct sums using numbers from the list that add up to t.For example,if t = 4,n = 6,and the list is [4,3,2,2,1,1],then there are four different sums that equal 4:4,3+1,2+2,and 2+1+1.(A number can be used within a sum as many times as it appears in the list,and a single number counts as a sum.) Your job is to solve this problem in general.
Input
The input file will contain one or more test cases,one per line.Each test case contains t,the total,followed by n,the number of integers in the list,followed by n integers x 1 ,...,x n .If n = 0 it signals the end of the input; otherwise,t will be a positive integer less than 1000,n will be an integer between 1 and 12 (inclusive),and x 1 ,...,x n will be positive integers less than 100.All numbers will be separated by exactly one space.The numbers in each list appear in nonincreasing order,and there may be repetitions.
Output
For each test case,first output a line containing `Sums of',the total,and a colon.Then output each sum,one per line; if there are no sums,output the line `NONE'.The numbers within each sum must appear in nonincreasing order.A number may be repeated in the sum as many times as it was repeated in the original list.The sums themselves must be sorted in decreasing order based on the numbers appearing in the sum.In other words,the sums must be sorted by their first number; sums with the same first number must be sorted by their second number; sums with the same first two numbers must be sorted by their third number; and so on.Within each test case,all sums must be distinct; the same sum cannot appear twice.
Sample Input
4 6 4 3 2 2 1 1
5 3 2 1 1
400 12 50 50 50 50 50 50 25 25 25 25 25 25
0 0
Sample Output
Sums of 4:
4
3+1
2+2
2+1+1
Sums of 5:
NONE
Sums of 400:
50+50+50+50+50+50+25+25+25+25
50+50+50+50+50+25+25+25+25+25+25

The sum of n different positive integers is less than 50.The greatest possible value of n is（ ）

C++麻烦解释一下题目意思
Description:A sequence of n （n> 0) integers is called a jolly jumper if the absolute values of the difference between successive elements take on all the values 1 through n-1. For instance, 1 4 2 3 is a jolly jumper, because the absolutes differences are 3, 2, and 1 respectively. The definition implies that any sequence of a single integer is a jolly jumper. You are to write a program to determine whether or not each of a number of sequences is a jolly jumper.
Input:Each line of input contains an integer n (n< 3000) followed by n integers representing the sequence.
Output:
For each line of input, generate a line of output saying "Jolly" or "Not jolly". Sample Input:4 1 4 2 3
5 1 4 2 -1 6Sample Output:Jolly
Not jolly
