In this post, we will be seeing how you can delay a method call using Swift. Here we will be seeing how you can achieve the same in two ways, So let’s get started, We will be seeing both the example in Playground, Step 1 − Open Xcode → New Playground.In the first approach, we will be using asyncAfter(deadline: execute:) instance method, which Schedules a work item for execution at the specified time and returns immediately.You can read more about it here https://developer.apple.com/documentation/dispatch/dispatchqueue/2300020-asyncafterStep 2 − Copy the below code in Playground and run, func functionOne() { let delayTime = ...

In this tutorial, we are going to write a program which finds all the occurrences of the 1(0+1) in a string using the regexes. We have a re module in Python which helps us to work with the regular expressions.Let's see one sample case.Input: string = "Sample 1(0+)1 string with 1(0+)1 unnecessary patterns 1(0+)1" Output: Total number of pattern maches are 3 ['1(0+)1', '1(0+)1', '1(0+)1']Follow the below steps to write the code for the program.Algorithm1. Import the re module. 2. Initialise a string. 3. Create a regex object using regular expression which matches the pattern using the re.compile(). Remember to ... Read More
We have to check whether two halves of a string have the same set of characters or not in Python. The frequency of the characters in the two halves must be identical. If the length of the string is odd, ignore the middle and check for the remaining characters. Follow the below steps to write code for the program.Algorithm1. Initialize a string. 2. Initialize an empty dictionary variable alphabets. 3. Initialize a variable mid with length / 2. 4. Write a loop until mid element. 4.1. Initialize the corresponding dictionary item by alphabets[char] with one if it's not initialized. ... Read More
