# How Do You Know If Two Numbers Have The Same Number?

## What is the sign of the quotient of two negative numbers?

RULE 3: The quotient of two negative integers is positive.

If the signs are different the answer is negative..

## What does special number mean?

What is Special Number. A number is known as Special number when sum of the factorial of digits is equal to the original number (given number). Examples: Below are examples of numbers which are Special. Number to check : 145 1!

## How do you find the frequency of a number in a number in Java?

int inputNumber = sc. nextInt(); Step 2 : Define one HashMap object called digitCountMap which will hold the digits as keys and their frequency as values.

## When the integers have the same sign what do u do?

Same Sign – Add the absolute values and give the answer the same sign. Subtracting Integers – Same as adding the opposite of that integer number.

## How do you compare digits in Java?

Syntax : public static int compare(int x, int y) Parameter : x : the first int to compare y : the second int to compare Return : This method returns the value zero if (x==y), if (x < y) then it returns a value less than zero and if (x > y) then it returns a value greater than zero.

## Is a special number?

Special Numbers in Java are ones whose sum of factorials of digits is equal to the number itself. It can be an N digit number. The program has to first break the number into its corresponding digits and calculate their factorials. … If the sum matches the original number then the number is called to be a Special number.

## How do you know if two numbers have the same sign?

Multiply the two number together. If the sign of the result is positive, then the sign was the same. If the sign of the result is negative, then the signs were different.

## How do you know if a number is a 2 digit number?

Approach: Extract the first and last digit of the number and add and multiply the digits separately. Then, add the sum and product of the digits of the two-digit number and compare it to the original number. If they are same, then it is a Special Two-Digit Number, else it is not.

## What is a Repdigit number?

In recreational mathematics, a repdigit or sometimes monodigit is a natural number composed of repeated instances of the same digit in a positional number system (often implicitly decimal). The word is a portmanteau of repeated and digit. Examples are 11, 666, 4444, and 999999.

## Can XOR be negative?

The XOR of x and y will have the sign bit as 1 iff they have opposite sign. In other words, XOR of x and y will be negative number number iff x and y have opposite signs.

## How do you count digits in Python?

Python Program to Count the Number of Digits in a NumberTake the value of the integer and store in a variable.Using a while loop, get each digit of the number and increment the count each time a digit is obtained.Print the number of digits in the given integer.Exit.

## How do you find a special number?

A number is said to be Special if the sum of the factorial of its digits is equal to the original number. Ex – 145. To check for special number in Java, we need first calculate the factorial of its digits and then sum it up.

## How do you know if a number has the same number?

Given two integers A and B, the task is to check whether both the numbers have equal number of digits. Approach: While both the numbers are > 0, keep dividing both the numbers by 10. Finally, check if both the numbers are 0. If any one of them is not 0 then they had unequal number of digits.

## How do you check if two numbers have the same number in Python?

Comparison of two numbers, #!/usr/bin/python def same_digits(a, b): if sorted(str(a)) == sorted(str(b)): print “{0} If you want to match true regardless of the number of each digit, then use set to the same unless you update d to equal the new length each time, and check if​ 1) Do the digit count check first.
