问题 My data set has a {Invoice No} field that I want to sum the cost of. All invoice numbers are unique and have one cost value. However, because there are multiple {Part No} fields in each {Invoice No}, Quicksight multiplies this one cost by however many part numbers there are in each invoice, so the sum ends up being some multiple of the real value that I want. This is what the table view looks like: {Invoice No} {Part No} {cost} 12345 001 10.12 12345 002 10.12 12345 003 10.12 How can I just

问题 I'm new to PHP and I have spent several hours researching and trying to figure out what I'm doing wrong. I'm joining several tables to populate a client profile page with multiple transactions from a transactions table. The rest of the page is working with the query as expected, but when using a while statement, each transaction in the result is repeating equal to the total number of transactions in the result. For instance, if the result has 3 transaction numbers (1, 2, 3), the while

问题 I have tried following this previous question: Comparing 2 Image's sources in Javascript However, there is no solution to this on the page I am trying to generate random images from 2 arrays, the same image can not be compared to each other. Duplicates continue to appear when i run this code from the if statement. However, what i intended to happen if if the same image is generated then a new pair of images would be displayed, and the duplicates would not be displayed. function start2AFC() {

问题 How to find the duplicate element in an array which is having lacks of elements? If I iterate the array for lacks of times the performance will became slow. What is the best way to iterate an array in efficient way? Or else can we use any other Java collection object to find the duplicates with less number of iterations or less time complexity? 回答1: You can use a HashSet because Sets don't allow duplicates, just loop over array of elements and insert them into a HashSet using the add() method

问题 I have got in one string like 800 adress emails. They are separated by semicolon. How should I do it to delete duplicates in that string? 回答1: Please update your question to show what you have already tried. It is very possible that your current code only needs a bit of tweaking. Below is a more general way to accomplish what you're after, but like I said, there may be an easier way to fix your current code and you won't really learn by copying and pasting code. Function RemoveDuplicates(rng
