In this article, We are going to learn about code and algorithm to check whether a number is palindrome or not in go golang. A palindrome number is a number which remains the same when it’s digits are reversed.
There are many ways to to check whether a number is palindrome or Not in go golang
1:)
Example:
1331 is a palindrome number because reverse of 1331 is 1331.
123 is not a palindrome number because reverse of 123 is 321 . After reversing the number, they are not equal.
Algorithm:
- Get the number as input from user.
- Reverse the number and store into a temp variable.
- Compare temp variable to number. If both are equal then it is a palindrome number else not.
Code:
package main import "fmt" func main(){ var number int var reverse_no int = 0 fmt.Print("Enter the number: ") fmt.Scan(&number) tmp_number := number for { remainder := tmp_number % 10 reverse_no = reverse_no * 10 + remainder tmp_number = tmp_number / 10 if (tmp_number == 0) { break } } if (reverse_no == number) { fmt.Printf("%d is a palindrome number", number) } else { fmt.Printf("%d is not a palindrome number", number) } }
Output:
Enter the number: 121
121 is a palindrome number.
Enter the number: 132
132 is not a palindrome number.
