根据以上数据,我们可以计算出end_date应该为2018年6月20日
我需要帮助编写算法/公式来计算基于日历的可变输入数据的结束日期。
任何建议将不胜感激。
答案 0 :(得分:0)
最后,我想出了一个非常简单的红宝石方法
const [result1 ,result2]= await funcName(arg)
通过调用这样的方法
def session_dates(date, weekdays_arr, number_of_working_days)
result = []
while result.size < number_of_working_days
if weekdays_arr.include? date.wday
result << date
end
date += 1
end
result
end
我可以在输出中获取工作日的所有日期
start_date = Date.today.beginning_of_month
session_days_in_week = [0,1,2,3,4,5,6] # week starts from 0(Sunday)
result = session_dates(start_date, session_days_in_week, 20)
显然结果数组中的最后一个元素是ending_date。
