问题 I am trying to get the last seven days on the x-axis of my line-chart (using chartjs). What is the best way to do this? Thanks 回答1: You can instantiate a chart for the last seven days with the following code: let start = new Date(), end = new Date(); start.setDate(start.getDate() - 7); // set to 'now' minus 7 days. start.setHours(0, 0, 0, 0); // set to midnight. new Chart(document.getElementById("chart"), { type: "line", options: { scales: { xAxes: [{ type: "time", time: { min: start, max:

Fastest way to find out a number with most divisors

只愿长相守 提交于 2021-02-07 10:28:10
问题 Given a number n how fast can one find the smallest number with most factors and is less than n? PS:other than the naive approach of finding number of divisors for all numbers upto n . UPDATE : My observation: int solve(int primes[],int s,int n) { int i=0; while(s<n) { s*=primes[i]; i++; } if(s>n) s/=primes[i-1]; return s; } int main() { int primes[] = {2,3,5,7,11,13,17,19,23,29,31,37}; int n; scanf("%d",&n); int s=1; while(s*2<n)//checking the possibility of existence of any prime such that

问题 How to get the current date in unix-epoch ? timeIntervalSince1970 prints the current time. Is there any way to get today's time at 12 AM? For example, The current time is : Jan 7, 2018 5:30 PM. timeIntervalSince1970 will print the current time i.e. 1546903800000 . Current date in epoch system will be Jan 7, 2018 00:00 AM. i.e 1546848000000 回答1: I would do this with components. Assuming you need time in seconds as defined by time(2). If you need in milliseconds as defined by time(3), then you

Could anybody help me out? So in semi-psuedo: q = db.GqlQuery("SELECT * FROM Kudo WHERE fromuser =

Measure execution time of docker container

谁说我不能喝 提交于 2021-02-07 02:56:28
问题 I have a docker image called my_image which launch a command and closes. When running the image in a container using command docker run --rm my_image , is it possible to measure the execution time of the container ? Edit : I need to see those timing information after container execution, thus I can't use time command. I somehow hoped to find some container execution history kept by docker even if --rm was used. But if it doesn't exist, then @tgogos' answer is suited. The goal is to compare
