算法实现题1-2 连续和问题
« 问题描述：
给定一个正整数n，计算有多少个不同的连续自然数段，其和恰为n。例如，当n=27
时，有4 个不同的连续自然数段的和恰为27：2+3+4+5+6+7；8+9+10；13+14；27。
« 编程任务：
给定一个正整数n，试设计一个O(n)时间算法，计算有多少个不同的连续自然数段的
和恰为n。
« 数据输入：
由文件input.txt提供输入数据。文件的第1 行是正整数n。
« 结果输出:
程序运行结束时，将计算出的和恰为n的连续自然数段的个数输出到output.txt中。
输入文件示例 输出文件示例
input.txt 27
output.txt 4
-Algorithm 1-2 consecutive title and the issue of ?Descr iption of the problem: given a positive integer n, calculate the number of consecutive natural number of different paragraph, and its and exactly n. For example, when n = 27, there were four different sections for natural and exactly 27:22 B! 3+ 4+ 5+ 6+ 7 8+ 9+ 10 13+ 14 27. ?Programming tasks: Given a positive integer n, try to design a O (n) time algorithm to calculate the number of different section of consecutive natural numbers and exactly n. ?Data input: from file input.txt to provide input data. Paragraph 1 line is a positive integer n. ?The results output: program to run at the end will be calculated and exactly the consecutive natural number n the number of paragraphs in the output to output.txt. Sample input file output file example input.txt 27 output.txt 4
