Hướng dẫn how can i print even and odd numbers in php? - làm cách nào để in số chẵn và lẻ trong php?

Ngày 27 tháng 7 năm 2016

Để in các số chẵn và số lẻ, chúng ta có thể sử dụng các loại phương thức khác nhau. Giá trị của nó tăng thêm 2 cho các số in chẵn.
Method:1
Even numbers between 1 to 100
In first method we use ‘for’ loops to print even numbers between 1 to 100. Here loop starts from number 2 and after every count its value increment by 2 for print even numbers.

<?php
echo "Even numbers between 1 to 100 :- ";
    for ($j=2; $j<=100; $j+=2){
        echo $j.", ";
    }
?>

Các số lẻ từ 1 đến 100 trong phương pháp đầu tiên, chúng tôi sử dụng ‘cho các vòng lặp để in các số lẻ trong khoảng từ 1 đến 100. Ở đây vòng lặp bắt đầu từ số 1 và sau mỗi lần tính giá trị của nó tăng 2 cho các số lẻ.
In first method we use ‘for’ loops to print odd numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 2 for print odd numbers.

<?php
echo "Odd numbers between 1 to 100 :- ";
    for ($j=1; $j<=99; $j+=2){
        echo $j.", ";
    }
?>

Phương pháp: 2Ven Số từ 1 đến 100 trong phương pháp thứ hai, chúng tôi sử dụng 'cho' vòng lặp và 'if' để in số chẵn từ 1 đến 100. Ở đây vòng lặp bắt đầu từ số 1 và sau mỗi lần tính giá trị của nó tăng 1, khi 'nếu' 'Điều kiện sẽ đúng, nó in thậm chí số.
Even numbers between 1 to 100
In second method we use ‘for’ loops and ‘if’ condition to print even numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 1, when ‘if’ condition will be true, it print even numbers.

<?php
echo "Even numbers between 1 to 100 :- ";
	for ($j=1; $j<=100; $j++){
		if( $j%2==0){
		echo $j.", ";
		}
	}
?>

<?php

Độ phức tạp về thời gian: O (n)

Sử dụng thao tác bit: Trong phương pháp này, chúng ta sẽ tìm thấy bit khôn ngoan và số lượng với 1. Nếu bit khôn ngoan và là 1, thì số này là số lẻ, khác thậm chí.

Input : 42
Output : Even
Explanation: The number 42 is divisible by 2

Input : 39
Output : Odd
Explanation: The number 39 is not divisible by 2

Dưới đây là việc thực hiện ý tưởng trên.{IDE} first, before moving on to the solution.

function

<?php
echo "Odd numbers between 1 to 100 :- ";
    for ($j=1; $j<=99; $j+=2){
        echo $j.", ";
    }
?>

<?php
echo "Odd numbers between 1 to 100 :- ";
    for ($j=1; $j<=99; $j+=2){
        echo $j.", ";
    }
?>

<?php
echo "Odd numbers between 1 to 100 :- ";
	for ($j=1; $j<=100; $j++){
		if( $j%2!=0){
		echo $j.", ";
		}
	}
?>

1. <?php
   echo "Odd numbers between 1 to 100 :- ";
       for ($j=1; $j<=99; $j+=2){
           echo $j.", ";
       }
   ?>
   

   3

   <?php
   echo "Odd numbers between 1 to 100 :- ";
       for ($j=1; $j<=99; $j+=2){
           echo $j.", ";
       }
   ?>
   

   04

   <?php
   echo "Odd numbers between 1 to 100 :- ";
       for ($j=1; $j<=99; $j+=2){
           echo $j.", ";
       }
   ?>
   

   05: This is the simplest method of checking for even and odd and in this method, we simply check whether the number is divisible by 2 or not using the modulo ‘%’ operator.

2. Phương pháp đệ quy: Trong cách tiếp cận đệ quy, chúng ta giảm số xuống 2 trong mỗi cuộc gọi đệ quy. Nếu số cuối cùng là 0 thì nó thậm chí là 1, kết quả sẽ là lẻ.: In the recursive approach, we reduce the number by 2 in each recursive call. If the final number is 0 then its even or else it is 1, the result will be odd.

3. Sử dụng thao tác bit: Trong phương pháp này, chúng ta sẽ tìm thấy bit khôn ngoan và số lượng với 1. Nếu bit khôn ngoan và là 1, thì số này là số lẻ, khác thậm chí.
   In this method we will find bit-wise AND of the number with 1. If the bit-wise AND is 1, then the number is odd, else even.
