How do you make a program reverse a number?
Let’s see a simple c example to reverse a given number.
- #include
- int main()
- {
- int n, reverse=0, rem;
- printf(“Enter a number: “);
- scanf(“\%d”, &n);
- while(n!=0)
- {
What 4-digit number times 4 equals itself backwards?
Answers. The Number is 2178.
How do you solve a 4-digit number?
Multiplying 4-Digit Numbers Quickly
- Write down both 4-digit numbers above each other.
- Multiply the first number by each digit of the second.
- Carry any numbers larger than 9, and finally.
- Add the results.
How many possibilities are there for a 4-digit code with 4 numbers?
Thanks for the A2A. If my understanding is correct, the question is referring to the standard 4-digit locks (which has numbers from 0–9). Answer: There are 9,999 different combinations in a 4-digit lock.
How do you reverse a 4 digit number in Python?
Reverse Number In Python
- # Python Program to Reverse a Number using While loop.
- Number = int(input(“Please Enter any Number: “))
- Reverse = 0.
- while(Number > 0):
- Reminder = Number \%10.
- Reverse = (Reverse *10) + Reminder.
- Number = Number //10.
- print(“\n Reverse of entered number is = \%d” \%Reverse)
How do you print in reverse order numbers?
Write a program in C to display the number in reverse order.
- Pictorial Presentation:
- Sample Solution:
- C Code: #include void main(){ int num,r,sum=0,t; printf(“Input a number: “); scanf(“\%d”,#); for(t=num;num!=0;num=num/10){ r=num \% 10; sum=sum*10+r; } printf(“The number in reverse order is : \%d \n”,sum); }
What number is reversed when multiplied by 4?
To summarize, the only number that solves the puzzle is 2178. By a similar logic, we can find the six-digit number that when multiplied by 4 is equal to the original number with its digits in reverse order. Each of the intermediate carries must be 3, and so the number is 219978.
How do you reverse a 4-digit number?
Reverse of a 4-digit number: Taking the last digit every time and multiplying with 10 and dividing the number by 10 every time and repeating the loop. Btw, the above program works not just for a 4-digit number, but with any number.
How do you calculate the number reverse in a loop?
The issue is your loop size, not your logic. Assuming all your numbers are 4 digits, then int reverse = 0; int i; for( i = 0; i < 4 ; i++ ) { reverse = reverse * 10; reverse = reverse + num\%10; num = num/10; } System.out.println(reverse);
What is the formula to calculate the reverse of a number?
Assuming all your numbers are 4 digits, then int reverse = 0; int i; for( i = 0; i < 4 ; i++ ) { reverse = reverse * 10; reverse = reverse + num\%10; num = num/10; } System.out.println(reverse); will work Share Improve this answer Follow
How to reverse the digits of an integer in JavaScript?
Write a program to reverse the digits of an integer. Time Complexity: O (log (n)), where n is the input number. Time Complexity: O (log (n)) where n is the input number. We will convert the number to a string using StringBuffer after this, we will reverse that string using the reverse () method
