I have a text where I would like to remove all uppercase consecutive characters up to a colon. I have only figured out how to remove all characters up to the colon itself; which results in the current output shown below.

Input Text

I am trying to divide the string with *, and return the divided strings, as follows.

So, I have the question of how to ignore \ operator inside the string in dart. I want to get a sample string "abcde\fg\hijk" without taking this as an operator. Now I am getting something like that "abcdefghijk" (without backslashes, I don't want that )

I have a dictionary which contains key and items model for the values.

var selectedDic: [String: [Item]] = [:]

• Actually I am trying to make a string with dictionary key and key has multiple value separated by comma.
• And if I add more values to key it should add values to specific key.
• price and publisher are keys and itemId is the value.

I need this string: price:10-25;publisher:576,925,1737

Am Kind of new to MySql and am trying to retrieve a query but got struck for some time.

Sample data set:

I have a cassandra debug.log. It has a lot of SELECT * queries that are not fired by any application. Applications request specific fields in SELECT queries, also the queries seem to have a LIMIT 5000 clause which I am pretty sure is not there in any application. Are these queries fired by cassandra internally? The debug log is filled with such queries. The application uses gocql driver to connect to cassandra.

According to this question, I would like to get the proportion of item in total amount, and display a pie chart like below(need to display the name and the proportion of the item):

I use the same dataset as the question:

Supposed I have some data as below:

I tried using awk splitting the columns to print a sentence but the first column has spaces.
