Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in reverse binary. For an integer x, the algorithm is:As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2Note: The above algorithm outputs the 0's and 1's in reverse order.Ex: If the input is:6the output is:0116 in binary is 110; the algorithm outputs the bits in reverse.
Question
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in reverse binary. For an integer x, the algorithm is:As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2Note: The above algorithm outputs the 0's and 1's in reverse order.Ex: If the input is:6the output is:0116 in binary is 110; the algorithm outputs the bits in reverse.
Solution
Here is a simple program that implements the algorithm described in the question:
def reverse_binary(n):
result = ''
while n > 0:
result += str(n % 2)
n = n // 2
return result
# Test the function
print(reverse_binary(6)) # Output: 011
This Python program defines a function reverse_binary that takes an integer n as input. It initializes an empty string result to store the binary representation. Then it enters a loop that continues as long as n is greater than 0. In each iteration of the loop, it calculates n % 2 (the remainder of n divided by 2), converts it to a string, and appends it to result. Then it updates n to be the integer division of n by 2. Finally, it returns result, which is the binary representation of the input number in reverse order. The last two lines of the program test the function with the input 6, and print the result.

algorithm for a program to reverse a number in c programming
Reverse bits of a given 32 bits unsigned integer.Note:Note that in some languages, such as Java, there is no unsigned integer type. In this case, both input and output will be given as a signed integer type. They should not affect your implementation, as the integer's internal binary representation is the same, whether it is signed or unsigned.In Java, the compiler represents the signed integers using 2's complement notation. Therefore, in Example 2 above, the input represents the signed integer -3 and the output represents the signed integer -1073741825. Example 1:Input: n = 00000010100101000001111010011100Output: 964176192 (00111001011110000010100101000000)Explanation: The input binary string 00000010100101000001111010011100 represents the unsigned integer 43261596, so return 964176192 which its binary representation is 00111001011110000010100101000000.Example 2:Input: n = 11111111111111111111111111111101Output: 3221225471 (10111111111111111111111111111111)Explanation: The input binary string 11111111111111111111111111111101 represents the unsigned integer 4294967293, so return 3221225471 which its binary representation is 10111111111111111111111111111111. Constraints:The input must be a binary string of length 32
Given a number x, reverse its binary form and return the answer in decimal.
Given a signed 32-bit integer x, return x with its digits reversed. If reversing x causes the value to go outside the signed 32-bit integer range [-231, 231 - 1], then return 0.Assume the environment does not allow you to store 64-bit integers (signed or unsigned). Example 1:Input: x = 123Output: 321Example 2:Input: x = -123Output: -321Example 3:Input: x = 120Output: 21 Constraints:-231 <= x <= 231 - 1
