Golang program to search a string in a sorted slice using SearchStrings() function

Here, we are going to learn how to search a string in a sorted slice using SearchStrings() function in Golang (Go Language)?
Submitted by Nidhi, on March 16, 2021

Problem Solution:

In this program, we will create a sorted slice of strings and then search an item into a slice using the sort.SearchStrings() function.

Program/Source Code:

The source code to search a string item in a sorted slice using the SearchStrings() function is given below. The given program is compiled and executed successfully.

// Golang program to search a string in a sorted slice
// using SearchStrings() function

package main

import "fmt"
import "sort"

func main() {
	slice := []string{"ABC", "LMN", "PQR", "XYZ"}
	item := "PQR"

	index := sort.SearchStrings(slice, item)

	if index < len(slice) && slice[index] == item {
		fmt.Printf("Item %s found at %d index", item, index)
	} else {
		fmt.Printf("Item %s not found", item)
	}
}

Output:

Item PQR found at 2 index

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the above program, we also imported the sort package to search a string item in sorted slice using sort. SearchStrings() function and get the index of item into the slice.

In the main() function, we created a sorted slice of strings. Then search item into slice using SearchStrings(). If an item is found in the slice then we will print the index of the item on the console screen.
