问题 On coding bat Logic-2, loneSum problem I typed in the first method listed below. It was right for all of the tests except for only one. The only one it failed on was where all of the variables equaled to the same integer. But when I looked up for the solution online I got the second method listed below and that worked. I think the only difference between my method and the right solution was the position of the "else if(a==b && b==c){return 0;}". My question is does the order of the conditions

问题 My code looks up values in one worksheet A in another worksheet B, and inputs data from a column in B if the values in A and B match. However, I am trying to copy those lines, where Vlookup returns #NA to the end of A data. The way I do it though, the for loop remains at the first index and copies an n-amount of lines with the first index content. Dim LastCol As Long Dim rng As Range Set rng = TargetWorksheet.Cells ' Use all cells on the sheet LastCol = Last(2, rng) ' Find the last col

问题 I need to check which one of 3 elements contains the text "10%" but I am not sure I am getting correctly the text of the element. When I run the code I am not getting errors but the if condition is always false(also when it should be true). My javascript code inside the spec: await driver.wait(until.elementIsVisible(await driver.findElement(By.css("tr:nth-child(1) .font-weight-bold-light > span"))), 30000) await driver.wait(until.elementIsVisible(await driver.findElement(By.css("tr:nth-child

问题 I have a data frame from a measurement where for each measurement a background is also measured: Wavelength Background_1 1 Background_2 2 ... 300 5 11 4 12 ... 301 3 12 5 10 ... ... ... ... ... ... ... I want to subtract the appropriate "Background_xyz" column from the corresponding column (e.g. subtract "Background_1" from "1". It would then look like this: Wavelength 1_corrected 2_corrected ... 300 6 8 ... 301 9 5 ... ... ... ... ... I can get this far no problem. The problem is, sometimes
