字符串排序

方法一：用sort排序，这样做体现不出什么知识点，出题人应该也不想考察这个
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
void (async function () {
// Write your code here
let tokens = [];
while ((line = await readline())) {
tokens.push(line);
}
let arr = tokens.slice(1, tokens.length);
arr.sort()
arr.forEach((item) => {
console.log(item);
});
})();
方法二：自己写排序算法和判断逻辑
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
void (async function () {
// Write your code here
let tokens = [];
while ((line = await readline())) {
tokens.push(line);
}
let arr = tokens.slice(1, tokens.length);
for (let i = 0; i < arr.length; i++) {
for (let j = 0; j < arr.length - 1 - i; j++) {
if (!func(arr[j], arr[j + 1], 0)) {
let temp = arr[j + 1];
arr[j + 1] = arr[j];
arr[j] = temp;
}
}
}
arr.forEach((item) => {
console.log(item);
});
function func(a, b, j) {
if (!a[j]) {
return true;
}
if (!b[j]) {
return false;
}
if (a[j] < b[j]) {
return true;
} else if (a[j] == b[j]) {
return func(a, b, j + 1);
} else {
return false;
}
}
})();
