5 min readIn Swift, a closure is a self-contained block of functionality that can be passed around and used in your code. Closures are similar to functions, but they do not require a name and can capture values from their surrounding context.To use closures in Swift, you can define a closure using curly braces {} and provide any necessary arguments and return type.

8 min readTo avoid late payments on installment loans, it is important to create a budget and stick to it to ensure that you have enough funds to make each payment on time. Set up automatic payments or reminders to stay on top of due dates and avoid missing them. Communicate with your lender if you anticipate any challenges in making a payment to explore potential solutions or alternative payment arrangements.

5 min readTo map over an array in Swift, you can use the map function. This function allows you to apply a transformation to each element in the array and return a new array with the transformed values.You can use the map function by calling it on the array and passing a closure as an argument. The closure should take each element of the array as an input parameter and return the transformed value.

5 min readIn Haskell, a non-binary tree is typically implemented using a datatype representing a tree structure with an arbitrary number of child nodes. Unlike a binary tree where each node has at most two children, a non-binary tree can have any number of child nodes.To implement a non-binary tree in Haskell, you can define a datatype that represents a tree node with a value and a list of child nodes. Each child node can itself be a tree node, allowing for the creation of a recursive tree structure.
-
6 min readTo filter an array in Swift, you can use the filter method. This method takes a closure as its argument, which specifies a condition that each element in the array must satisfy in order to be included in the filtered result. The closure should return a boolean value indicating whether the element should be included in the filtered array.

5 min readIf you want to repay an installment loan early, you can start by contacting your lender to see if there are any penalties or fees associated with early repayment. Next, you can calculate the total amount you owe, including any interest that has accrued. You can then make a lump sum payment to pay off the remaining balance of the loan. Be sure to confirm that your payment is applied to the principal balance and not just the interest.

2 min readTo reverse a nested list in Haskell, you can use the map function along with the reverse function to reverse each individual sublist and then reverse the entire list. This can be accomplished by mapping the reverse function over the nested list and then applying the reverse function to the resulting list. This will reverse the nested list in Haskell.[rating:98df3ae9-d3ec-4abe-9e48-d133cc42cdc2]What is the difference between reversing a list and reversing a nested list in Haskell.
-
3 min readTo sort an array in Swift, you can use the sort() or sorted() method. The sort() method sorts the array in place, while the sorted() method returns a new sorted array without modifying the original array. You can sort the array in ascending order by using the < operator inside the sort closure. Alternatively, you can sort the array in descending order by using the > operator.

4 min readTo calculate installment loan payments, you can use the formula for calculating the monthly payment on a loan.The formula is: PMT = [P × r(1 + r)^n] / [(1 + r)^n - 1]Where: PMT = monthly payment P = loan amount r = monthly interest rate (annual interest rate divided by 12) n = number of months for the loan termFirst, calculate the monthly interest rate by dividing the annual interest rate by 12. Then, plug in the values for P, r, and n into the formula to calculate the monthly payment.

6 min readTo check if a string contains a certain word in Haskell, you can use the isInfixOf function from the Data.List module. This function takes two parameters - the substring you want to check for and the string you want to search in. If the substring is found within the given string, the function returns True, otherwise it returns False. Here's an example of how you can use it: import Data.

4 min readIn Swift, you can iterate over a dictionary using a for loop. This loop will iterate over each key-value pair in the dictionary. You can access the key and value of each pair using the .key and .value properties.
