1、金币银币问题：有若干币值不同的金币和银币，任一金币的价值都大于所有银币，要求按价值由小到大排列所有货币。

模型分析：用数组存放所有的整数，奇数（偶数）代表金币，偶数（奇数）代表银币，按先偶后奇（先奇后偶）的顺序整理数组，然后分别对偶数列和奇数列进行排序。

将程序补充完整

2、十进制向任意进制（二进制，八进制，十六进制）数转换，输入十进制数n和一个进制类型x，将n转换为x进制输出-Gold coins: a number of different denominations of gold and silver coins, the value of any gold coins are greater than all the silver coins, the requirements of small to large order by value of all currency. Model: all integer stored in an array, odd (even) on behalf of the gold coins, even (odd) on behalf of silver, at first, even after the order of (first odd even odd) finishing the array, and then sort even columns and odd columns . Complete program supplements, decimal to any hex (binary, octal, hexadecimal) digital conversion, input decimal number n and a hex type x n converted to x binary output
