30秒学会 Golang 片段 – IsPalindrome

Returns true if the given string is a palindrome, false otherwise.

Use strings.Fields(), strings.Join() and strings.ToLower() to get the normalized, lowercase string without spaces.
Use range to iterate over the string and compare each rune to the one in the reversed string.

代码实现

import "strings"

func IsPalindrome(s string) bool {
    v := strings.ToLower(strings.Join(strings.Fields(s), ""))
    for i := range v {
        if v[len(v)-i-1] != v[i] {
            return false
        }
    }
    return true
}

使用样例

IsPalindrome("taco cat") // true
