Given a binary representation in the form of a string(s) of a number n, the task is to find a binary representation of n+1.Note: Output binary string should not contain leading zeros.Example 1:Input: s = "10"Output: 11Explanation: "10" is the binary representation of 2 and binary representation of 3 is "11"Example 2:Input: s = "111"Output: 1000Explanation: "111" is the binary representation of 7 and binary representation of 8 is "1000"Your Task: You don't need to read input or print anything. Complete the function binaryNextNumber()which takes s as input parameter and returns the string.Expected Time Complexity: O(n)Expected Auxiliary Space: O(n) to store resultant string Constraints:1 <= n <= 105
Solution
Here is a step-by-step solution to the problem:
-
Convert the binary string to an integer: Python has a built-in function
int()that can convert a binary string to an integer. You can use it like this:n = int(s, 2). The second argument2specifies that the string is a binary number. -
Increment the integer: Simply add 1 to the integer:
n = n + 1. -
Convert the integer back to a binary string: Python has a built-in function
bin()that can convert an integer to a binary string. You can use it like this:s = bin(n). This will return a string that starts with'0b'to indicate that it is a binary number. -
Remove the
'0b'prefix: You can use Python's string slicing to remove the first two characters:s = s[2:]. -
Return the result: The function
binaryNextNumber()should return the binary strings.
Here is the complete function:
def binaryNextNumber(s):
# Step 1: Convert the binary string to an integer
n = int(s, 2)
# Step 2: Increment the integer
n = n + 1
# Step 3: Convert the integer back to a binary string
s = bin(n)
# Step 4: Remove the '0b' prefix
s = s[2:]
# Step 5: Return the result
return s
This function has a time complexity of O(n) and uses O(n) auxiliary space to store the resultant string, as required by the problem statement.

Write a program that reads from the user 1 character representing a "1-digit" value in Hexadecimal Format. The program should print the corresponding BINARY representation of the input.For example:- '4' --> "0100".- '7' --> "0111".- 'A' --> "1010".The input values can be 0,1,2,3,...,A,B,C,D,E,F.
You are given a positive integer n.A binary string x is valid if all substrings of x of length 2 contain at least one "1".Return all valid strings with length n, in any order. Example 1:Input: n = 3Output: ["010","011","101","110","111"]Explanation:The valid strings of length 3 are: "010", "011", "101", "110", and "111".Example 2:Input: n = 1Output: ["0","1"]Explanation:The valid strings of length 1 are: "0" and "1".

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.
