import (
    "bufio"
    "os"
    "strings"
    "strconv"
)

func main() {

    in := bufio.NewReader(os.Stdin)
    out := bufio.NewWriter(os.Stdout)

    buffer, _ := in.ReadString('\n')
    str := []rune(strings.Trim(buffer, "\n"))

    buffer, _ = in.ReadString('\n')
    count, _ := strconv.ParseUint(strings.Trim(buffer, "\n"), 10, 0)
    for k := uint64(0); k < count; k++ {

        buffer, _ = in.ReadString('\n')
        flds := strings.Fields(buffer)

        if []rune(flds[0])[0] == 'c' {
            i, _ := strconv.Atoi(flds[1])
            str[i-1] = []rune(flds[2])[0]
        } else {
            i, _ := strconv.ParseUint(flds[1], 10, 0)
            j, _ := strconv.ParseUint(flds[2], 10, 0)
            if isPali(i-1, j-1, str) {
                out.WriteString("Yes\n")
            } else {
                out.WriteString("No\n")
            }
        }
    }
    out.Flush()
}

func isPali(i, j uint64, str []rune) bool {
    for i < j {

        if str[i] != str[j] {
            return false
        }

        i++
        j--
    }
    return true
}
