What you are looking for is called Recursion. Below is a recursive function that calls itself if the value of the array key is also an array. function printArrayList($array) { echo “<ul>”; foreach($array as $k => $v) { if (is_array($v)) { echo “<li>” . $k . “</li>”; printArrayList($v); continue; } echo “<li>” . $v . … Read more
Normally with recursion you’d have a function that calls itself. You don’t need recursion to reverse a string, but I suppose you could have a function that takes a string, and appends the first character of the string to the reverse of the rest. I’ll try to explain how this works without giving too much … Read more
Recursion is the foundation of computation, every possible program can be expressed as a recursive function (in the lambda calculus). Hence, understanding recursion gives you a deeper understanding of the principles of computation. Second, recursion is also a tool for understanding on the meta level: Lots of proofs over the natural numbers follow a pattern … Read more
set { TimeZone = value; } The setter is recursive. You must use a field like: string _timeZone; public string TimeZone { get { if (_timeZone== null) return “”; return _timeZone; } set { _timeZone= value; } } 1 solved Why would this simple code cause a stack overflow exception?
You need to return the value from you recursion… function nth(list, index){ console.log(index); if(index < 1){ console.log(“Success”, list.value); return list.value; } else { console.log(“Fail”); list = list.rest; index–; return nth(list,index); } } Think like this – Initial call I fails, so you recurse R1 and fail, then recurse R2 and succeed. You correctly return the … Read more
When len is static, it’s not every call to length increment the same variable. Here’s what happens 1-> 2-> 3-> 4-> 5 add 1 to length (length = 1) add 2 to length (length = 3) add 3 to length (length = 6) add 4 to length (length = 10) add 5 to length (length … Read more

public static long weightedSum(int[] a, int[] b, int n) { if (n == 0) return 0; else return a[n – 1] * b[n – 1] + weightedSum(a, b, n – 1); } Output : int[] arr1 = { 1, 2, 3, 4, 5 }; int[] arr2 = { 6, 7, 8, 9, 10 }; System.out.println(weightedSum(arr1, … Read more
Going by the if statements: fib(0) = 0 fib(1) = 1 fib(2) = fib(2-1) + fib(2-2) = fib(1) + fib(0) = 1 + 0 = 1 fib(3) = fib(3-1) + fib(3-2) = fib(2) + fib(1) = fib(2-1) + fib(2-2) + 1 = fib(1) + fib(0) + 1 = 1 + 0 + 1 = 2 … Read more
Functions return their value in $v0; the print integer syscall expects its argument in $a0. You need to move $a0 to $v0 before you do the print, otherwise you’ll be printing whatever happened to be in $a0 (which in the case is the last value that you recursively added; i.e. 10). solved the answer is … Read more
A count down method by recursion. The biggest problem is slowing the countdown so you can actually see the numbers change. For that we can use setInterval. so the code below is pretty simple. First define the end case, in this case when n=0. Update the innerHTML and quit (don’t return anything). ELSE return the … Read more
Here is a test application to show you the trace of the program’s execution (requires Java 11 due to the use of String#repeat(int)): public class Main { private static int depth; public static void main(String[] args) { foo(0); } public static void foo(int n) { printDebug(“Invoked foo(” + n + “)”); if (n < 2) … Read more
Let’s step through your code static void Main(string[] args) { int input = 7; int zeroes = 0; List<int> myList = ATM(input); mylist => [3,2,1] foreach(var number in myList.ToArray()) { if (number != 0) { myList.AddRange(ATM(number)); } else { continue; } after 3 mylist => [3,2,1,1,1,0] after 2 mylist => [3,2,1,1,1,0,1,0,0] after 1 mylist => … Read more
How to write a code in python that is a recursive function that returns a string with each character in its argument repeated? solved How to write a code in python that is a recursive function that returns a string with each character in its argument repeated?
In the end @Taplar had the suggestion for the appropriate solution. I had hoped to find a solution that worked with the code I shared originally which documentation can be found here: https://api.jquery.com/jQuery/#jQuery2. Unfortunately it appears to be a code style that hasn’t drawn the right person’s attention or it’s not widely liked. Here’s a … Read more
