## Overview
The Go language provides a built-in package named `math/rand` for generating pseudo-random numbers. 

**Pseudo-random** numbers are a deterministic sequence that depends on a seed value. To generate random numbers on every execution, we need to set the seed every time.

In this shot, we will use the `math/rand` package to generate a random number.

## Syntax
```
rand.Int()

rand.Intn(n)

rand.Float64() 
```
* `rand.Int()`: Returns a random integer.
* `rand.Intn(n)`: Accepts one argument, `n` (the upper bound), and will throw an error if the value of `n` is less than zero. `rand.Intn(n)` returns a random integer between 0 and `n`.
* `rand.Float64()`: Returns a random `float64` number between 0.0 and 1.0.

## Example


package main

import (
  "fmt"
  "math/rand"
  "time"
)

func main() {
  // seed to get different result every time
  rand.Seed(time.Now().UnixNano())
  
  fmt.Println(rand.Int())
  fmt.Println(rand.Int())
  fmt.Println(rand.Int())
  fmt.Println()
  fmt.Println(rand.Intn(50))
  fmt.Println(rand.Intn(50))
  fmt.Println(rand.Intn(50))
  fmt.Println()
  fmt.Println(rand.Float64())
  fmt.Println(rand.Float64())
  fmt.Println(rand.Float64())
}

How to generate random numbers in Go language

Use Go's math/rand package to generate pseudo-random numbers and set the seed for variability.
