const rl = require('readline').createInterface({input: process.stdin})
const iter = rl[Symbol.asyncIterator]()
const readline = async () => (await iter.next()).value

void async function () {
    const lines = parseInt(await readline())
    if (lines < 7 && lines >= 1){
        console.log(lines + 1)
    }else if (lines === 7){
        console.log( 1)
    }else{
        console.log('输入数字不在范围内')
    }

    rl.close()
}()
