How to Avoid Loops for Efficient Integer Input in Golang?

Efficient Integer Input in Golang: Avoid Explicit Loops

Intending to efficiently gather multiple integers separated by spaces and store them in a slice, let's explore a solution that bypasses explicit loop iterators.

Without using traditional for loops, we can employ a recursive approach to iteratively scan the input. Here's a breakdown of the strategy:

<br>func ReadN(all []int, i, n int) <br>

  • This function recursively iterates through the input slice, starting from a given index i and iterating until n values are obtained.

<br> if n == 0 {</p>
<pre class="brush:php;toolbar:false">    return
}

  • The recursion base case checks if we've reached the end of the desired values. If so, we return.

<br> if m, err := Scan(&all[i]); m != 1 {<br>

  • This line scans a single integer value into the slice element at index i.

<br>ReadN(all, i 1, n-1)<br>

  • After scanning a single value, we recursively call ReadN to obtain the next value. This process repeats until all values are inputted.

Utilizing the fmt.Scan function, which performs input parsing, this approach offers efficient scanning of integer inputs.

For even faster processing, we can replace func Scan(a *int) with an optimized function that leverages various tricks for accelerated input reading. This enhanced version further optimizes the input processing speed.

By employing these efficient techniques, we can swiftly read multiple integers from the user and store them in an integer slice, expediting the input processing workflow in Golang.
