问题 How to check if two series of dates overlap and determine the first date that it occurs? Imagine that I've created two events in Google Calendar. One of them in Date1 and repeating every X days; the other in Date2 and repeating every Y days. What would be the best algorithm to determine if the two series will overlap someday, and find the first date that it would happen? Example 1: Date1 = Feb-15, 2016 X = 14 (repeat every 14 days) Date2 = Feb-22, 2016 Y = 21 (repeat every 21 days) Result:

问题 I can't seem to find an elegant solution to finding ranges. For me, it would come down to this: > seq(1:10) [1] 1 2 3 4 5 6 7 8 9 10 I would like to get the reverse: function(c(1,2,3,4,5,6,7,8,9,10)) result 1:10 Real world problem is that I have 1200 indices, some are 0, some are 1: c(0,0,0,0,0,0,1,1,1,1,1,1,0,0,0,0,1,0,0,1,1,1,1,1,1,0,0,0,0,1,1,1,1,1) And I would like the ranges/coordinates within the vector for each set of 0s and 1s. 回答1: Will this simple solution work? > rev(seq(1:10)) [1]

问题 I have a sheet for every day in the month. At the end of every month, I need to sum the same cell across all tabs. The following works: =SUM(March31!L2,March30!L2,March29!L2,March28!L2,March26!L2,March25!L2,March24!L2) However, at the end of the month, the formula will be tremendous. Tried the following: =SUM(March31:March1!L2) Doesn't work. Is it even possible? 回答1: SUM(March31:March1!L2) that won't work, but you can use kind of a generator: ={" "; ARRAYFORMULA("=SUM("&TEXTJOIN(", ", 1, TEXT

问题 I have created a slider. In chrome everything is working fine.See image below: But in MS Edge, thumb appears behind track. See image below: I created a codepen to explain and show my problem : https://codepen.io/glalloue/pen/QGKqNd Css(less) applied : .form input[type=range] { z-index: 1; align-self: stretch; height: 3px; -webkit-appearance: none; appearance: none; border: none; margin: 0; &::-webkit-slider-thumb { -webkit-appearance: none; appearance: none; border: none; width: 2.5rem;

问题 I've looked all over Stackoverflow and it seems that all range sliders with thumb labels have this problem. For example, this answer almost doesn't have it, but still does. Basically, you can calculate value / max to get the left style for the range value label, so that it's always aligned to the thumb. The problem is that the further right you slide, the more offset it gets. For example, in the linked answer the label starts off on the left side of the thumb at the 0 value, and it slowly

问题 I looked over Python Docs (I may have misunderstood), but I didn't see that there was a way to do this (look below) without calling a recursive function. What I'd like to do is generate a random value which excludes values in the middle. In other words, Let's imagine I wanted X to be a random number that's not in range(a - b, a + b) Can I do this on the first pass, or 1. Do I have to constantly generate a number, 2. Check if in range() , 3. Wash rinse ? As for why I don't wish to write a
