guys. I'm having some issue in recursion where there's a part that's confusing the heck out of me.
this is the code:
int re(int i) { int j; j = i while(j <= 3) { re(i+1); j++;} }
Now from what I understand so far is the variable j within the function , which takes the value of the argument i o...
I'm new to Go, so I implemented a few sorting algorithms for practice. For example, I have an in-place insertion sort, and a bubble sort:
func bubbleSort(arr []int) {
for i := 1; i < len(arr); i++ {
if arr[i] < arr[i - 1] {
tmp := arr[i - 1]
arr[i - 1] = arr[i]

Using JSX syntax I wrote a function that takes either a float or an integer as a parameter and returns a formatted string. I'd like any feedback for refactoring the code.
const moneyFormat = (float) => {
let answer = [];
let firstHalf;
let secondHalf;
// check if whole number
if (floa...

How can efficiently check duplicate(only 2) in array and if duplicate found then replace the duplicate element with index(0 to n-1) value of the array.Please help.
I am writing an WinForms app to make automatic measurements. For it I have a DB with 2 tables (there are more tables there but aren't important for the problem) called Transmitter , which are the devices to be measured and Calibration, which are the measurements.
A Transmitter can have zero-One...
I want to solve this problem in functional programming (fp) way only. This is my fp approach:
Each new term in the Fibonacci sequence is generated by adding the
previous two terms. By starting with 1 and 2, the first 10 terms will
be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

Problem Statement
A network consisting of M cities and M − 1 roads connecting them is given. Cities are labeled with distinct integers within the range [0..(M − 1)]. Roads connect cities in such a way that each pair of distinct cities is connected either by a direct road or along a path consisti...
I don't remember the exact wording of the question, but it is clearly an activity selection problem, which is
[...] notable in that using a greedy algorithm to find a solution will always result in an optimal solution.
I put a rough description of the problem in the docstring, and present i...
This is the first draft of dqueue, a dynamic queue library written in C, with a sample program to demonstrate it.
This is my first time writing any sort of library to be used as a generic subsection of other projects, so I'm sort of guessing as to what additional considerations I should have tak...

Given a sorted dictionary (array of words) of an alien language, find
order of characters in the language.

The idea is to create a graph of characters and then find topological sorting of the created graph. Following are the detailed steps.
1) Create a graph g with number of vertice...
