[ad_1] The only tricky thing here is a comparison with tolerance, since because of round up errors you can well never meet answer == value condition. The implementation could be double answer = 300.0; double tolerance = 1e-10; while (true) { // based on previous answer we compute next one double value = 0.5 * … Read more
[ad_1] You probably want something like this SELECT Name, Composer, REPLACE(Composer,”https://stackoverflow.com/”,’,’) AS Make FROM tracks But it really is impossible to tell for sure given that you don’t tell us any of the table or field names in your database and very little about your database model [ad_2] solved Selecting more than one value
[ad_1] One approach is to use the tidy function from the broom package. It is versatile and can organize most R statistical results into a data frame. library(broom) set.seed(1) x <- rnorm(1000) x[sample(1:length(x), 100)] <- NA df <- tidy(summary(x)) df minimum q1 median mean q3 maximum NA’s 1 -3.008 -0.6834 -0.01371 0.00106 0.6978 3.81 100 … Read more
[ad_1] This isn’t working because you’re using globals. When you hit if tape[selectedCell] == int(”.join(num)): for the third if statement, nums contains [‘1’, ‘1’] because both if statements have added a 1 to num, so when you do int(”.join(num)) you end up with 11 which is not equal to 1. You need to refactor this … Read more
