How to take care naughty functions -> "Recursive"

When we play Recursive Function, we need precautions , because it's recursive in nature. There's a big problem if base condition not valid then it repeat infinite times. Which cause panic in go-lang. Today, I use simple example such as factorial

package main
import (
"fmt"
)
func main() {
i := fact(5)
fmt.Println(i)
}
func fact(n int)int {
if n == 1{
return n
}
return n * fact(n-1) } Play

If you're a detective then you may notice that in func fact return again fact. This line
actually recursive line which repeat over and over, until base condition are true

Rosicrucian cipher

In 1513 Cornelius Agrippa introduce early form Rosicrucian Cipher in his books Occult of Philosophy. Geometric and simple substitution cipher are well known ciphers Pigpen , Freemason, Napoleon and tic tac toe ciphers in which alphabets or symbols arrange in grids. This is an anagram, "How to reconstruct a data " lets encode the message. Pigpen cipher , Rosicrucian and Tic tac toe Cipher Thank you have a good day.

Life is all about decisions and repeat your routine

Life is all about Decisions and repeat our routine is an excellent idea which i show you within a moment. Everyday we take so many decisions based on environment conditions, circumstances. Each decision based on cause and effect philosophy. Programmer are wizards who create own world with data and structures. Without data or structure our world is nothing. Conditions: Conditions help us to take decision based under certain circumstances, such as if a number divisible by 2 at least two times then it's said to be double even. package main import ( "fmt" ) func main() { const divisible =2 var even int = 4 if even%divisible == 0 { n := even/divisible n /= divisible if n ==1 { fmt.Println("Doubly Even") } } } If you're a developer then you you know this code quite different from other languages syntax. In most languages, you see like this "if (condition)". Yeah it's different but this language compilati...

Without this Agent , mission doesn't accomplish?

If you play military games such as Delta force , IGI Project , commandos etc . You familiar about in your team. Each member of team are unique in their skills. Some are snipers , short gun , hackers, communication officer. Now I will introduce golang special agent which are quite helpful in most of time. Variadic Function will show in a moment! Variadic Function: Variadic Functions means a function that arguments varing. In variadic function ... called ellipsis. package main import ( "fmt" ) func main() { values := []int{1,2,3} fmt.Println("Value[0]",seriesAdd(values[0])) fmt.Println("Total", seriesAdd(values...)) } func seriesAdd(x ...int)int{ var count int = 0 for _, v := range x{ count+= v } return count } Conditions : Before passing to the variadic function array must be slice. ...
