Searching an integer item in a sorted slice using SearchInts() function in Golang

Problem Solution:

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

Program/Source Code:

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

Golang code to search an integer item in a sorted slice using SearchInts() function

// Golang program to search an integer item in a
// sorted slice using SearchInts() function

package main

import "fmt"
import "sort"

func main() {
	slice := []int{10, 20, 30, 40, 50, 60, 70}
	item := 50

	index := sort.SearchInts(slice, item)

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

Output:

Item 50 found at 4 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 an item in sorted slice using sort. SearchInts() function and get the index of item into a slice.

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