设计一个预测股票最佳买卖时机的程序。 输入8天的某股票预测价格，保存在数组a中，a[i]是某股票第 i 天的预测价格。 编程寻找买入与卖出的最佳时机，使获取的收益最大化。（注意:最多只能买卖一次） (如果有多种收益相同的最佳方案，输出一种即可。如果无收益方案，则输出“不推荐买入”。 ) 例如，输入：3 3 5 8 2 3 1 4 输出：最佳时机：第1天买入、第4天卖出 （注意：程序有3个空，一个答案一行，不要添加多余的字符与空格） #define N 8 #include ＜stdio.h＞ int main() { int i,j,max,no1,no2,diff; float a[11]; for(i=1;i＜=n;i++) scanf("%f",&a[i]); max="0;" no1="1;" no2="2;" for(i="1;i<=N-1;i++)" for(j="i+1;j<=N;j++)" { diff=";" 保存当前最佳买入时间（第几天） 保存当前最佳卖出时间（第几天） } if(max!="0)" printf("第%d天买入、第%d天卖出",no1,no2); else printf("不推荐买入");＞
