Tìm số nhỏ nhất trong mảng javascript cho vòng lặp

Có nhiều phương pháp để tìm các số nhỏ nhất và lớn nhất trong một mảng JavaScript và hiệu suất của các phương pháp này thay đổi dựa trên số lượng phần tử trong mảng. Hãy thảo luận riêng về từng vấn đề và đưa ra kết quả thử nghiệm cuối cùng

Đối với các mảng thông thường, bạn có thể sử dụng Math. tối đa với ba dấu chấm

let max = Math.max(...arrayOfNumbers);

Toán Javascript. max tìm max trong mảng

hãy để arrayOfNumbers = [4, 12, 62, 70, -10]; . nhật ký (Toán. tối đa (. arrayOfNumbers));

Sử dụng dấu ba chấm (…) giúp dễ dàng gọi bất kỳ hàm nào cần đối số

Toán học. hàm max sử dụng phương thức apply() để tìm phần tử lớn nhất trong một mảng số

Math.min.apply(Math, testArr);
Math.max.apply(Math, testArr);

Toán Javascript. tối đa. áp dụng tìm phần tử max trong mảng

hãy để arrayOfNumbers = [4, 12, 62, 70, -10]; . nhật ký (Toán. tối đa. áp dụng (Math, arrayOfNumbers));

Toán tử cũng được sử dụng để lấy giá trị lớn nhất của một mảng. Nó mở rộng một mảng số vào danh sách các đối số, chẳng hạn như với Math. tối thiểu () và Toán. tối đa()

Math.min(...testArr);
Math.max(...testArr);

Math.min.apply(Math, testArr);
Math.max.apply(Math, testArr);

Bạn có thể sử dụng vòng lặp tiêu chuẩn cho hàng tấn đối số vì vòng lặp for không có giới hạn về kích thước

let max = testArray[0];
for (let i = 1; i < testArrayLength; ++i) {
  if (testArray[i] > max) {
    max = testArray[i];
  }
}

let min = testArray[0];
for (let i = 1; i < testArrayLength; ++i) {
  if (testArray[i] < min) {
    min = testArray[i];
  }
}

Javascript vòng lặp tiêu chuẩn tìm phần tử tối đa trong mảng

cho arrayList = [1, 2, 3, 4, 3, 21, 0]; . chiều dài; . nhật ký (tối đa);

Bạn cũng có thể sử dụng phương thức reduce() để lấy số lượng mục

testArr.reduce(function (a, b) {
  return Math.max(a, b);
});
testArr.reduce(function (a, b) {
  return Math.min(a, b);
});

Phương thức Javascript reduce() để lấy số mục tối đa ar tối thiểu

hãy để mảngList = [1, 2, 3, 4, 3, 20, 0]; . giảm ((trước, hiện tại) => { trả về Toán học. max(trước, hiện tại) }); . nhật ký (maxNum);

Các phương thức áp dụng và trải rộng có giới hạn là 65536 xuất phát từ giới hạn số lượng đối số tối đa. Vào năm 2019, giới hạn là kích thước tối đa của ngăn xếp cuộc gọi, nghĩa là kích thước tối đa cho các số trong trường hợp áp dụng và giải pháp trải rộng là khoảng 120000. Tập lệnh sau sẽ tính toán giới hạn cho môi trường cụ thể của bạn

let testArr = Array.from({
  length: 10000
}, () => Math.floor(Math.random() * 2000000));
for (i = 10000; i < 1000000; ++i) {
  testArr.push(Math.floor(Math.random() * 2000000));
  try {
    Math.max.apply(null, testArr);
  } catch (e) {
    console.log(i);
    break;
  }
}

Khi bạn kiểm tra tất cả các ví dụ đã cho ở trên, kết quả cho thấy vòng lặp tiêu chuẩn là nhanh nhất. Sau đó đến các phương pháp áp dụng và lây lan, sau chúng là giảm, đây là phương pháp chậm nhất. When dealing with large arrays of more than 40 elements, the spread operator is considered a worse choice compared to other methods

A Simple Solution is to sort the array in increasing order. The first two elements in the sorted array would be the two smallest elements. In this approach, if the smallest element is present more than one time then we will have to use a loop for printing the unique smallest and second smallest elements.  

Below is the implementation of the above approach
