In Go language slice is more powerful, flexible, convenient than an array, and is a lightweight data structure. The slice is a variable-length sequence which stores elements of a similar type, you are not allowed to store different type of elements in the same slice.
In the Go slice, you can search an element of int type in the given slice of ints with the help of SearchInts() function. This function searches for the given element in a sorted slice of ints and returns the index of that element if present in the given slice. And if the given element is not available in the slice(it could be len(s_slice)), then it returns the index to insert the element in the slice. The specified slice must be sorted in ascending order. It is defined under the sort package so, you have to import sort package in your program for accessing SearchInts function.
Syntax:
func SearchInts(s_slice []int, i int) int
Example 1:
// Go program to illustrate how to search // an int type element in the slice of ints package main import ( "fmt"
"sort"
) // Main function func main() { // Creating and searching an element
// in the given slice of ints
// Using SearchInts function
res1 := sort.SearchInts([] int {1, 2, 3,
4, 5, 6, 7, 8}, 5)
res2 := sort.SearchInts([] int {200, 300,
400, 500, 600, 700}, 400)
// Displaying the results
fmt.Println( "Result 1: " , res1)
fmt.Println( "Result 2: " , res2)
} |
Output:
Result 1: 4 Result 2: 2
Example 2:
// Go program to illustrate how to search an // element of int type in the slice of ints package main import ( "fmt"
"sort"
) // Main function func main() { // Creating and initializing
// slice of ints using the
// shorthand declaration
slice_1 := [] int {34, 67, 78, 10, 43, 67, 8}
slice_2 := [] int {100, 500, 300, 600, 900, 1000}
var f1, f2, f3 int
f1 = 67
f2 = 300
f3 = 100
// Sorting the given slice of ints
sort.Ints(slice_1)
sort.Ints(slice_2)
// Displaying the slices
fmt.Println( "Slice 1: " , slice_1)
fmt.Println( "Slice 2: " , slice_2)
// Searching a int type element
// in the given slice using
// the SearchInts function
res1 := sort.SearchInts(slice_1, f1)
res2 := sort.SearchInts(slice_2, f2)
res3 := sort.SearchInts(slice_2, f3)
// Displaying the results
fmt.Println( "Result 1: " , res1)
fmt.Println( "Result 2: " , res2)
fmt.Println( "Result 3: " , res3)
} |
Output:
Slice 1: [8 10 34 43 67 67 78] Slice 2: [100 300 500 600 900 1000] Result 1: 4 Result 2: 1 Result 3: 0
