Check if a String is Palindrom or not

Efficient Approach

package main

import "fmt"

func main() {
    str := "日本語本日" // true
    // str := "日本語語本" // false
    // str := "日本語語本日" // true
    // str := "madam" // true
    // str := "maddam" // true
    result := isPalindram(str)
    fmt.Println(result)

}

func isPalindram(str string) bool {
    chars := []rune(str)
    for i := 0; i < len(chars)/2; i++ {
        revIdx := len(chars) - i - 1
        if chars[i] != chars[revIdx] {
            return false
        }
    }
    return true
}
