Given a binary string str consisting of characters ‘0’ and ‘1’. The task is to find whether the string is valid or not. A string is valid only if the characters are alternating i.e. no two consecutive characters are same.
Input: str = “010101”
Input: str = “010010”
Approach: Start traversing the string character by character and if there are any two consecutive characters that are equal then print Invalid else print Valid in the end.
Below is the implementation of the above approach:
- Check if a binary string has two consecutive occurrences of one everywhere
- Python | Check if there are K consecutive 1's in a binary number
- Check if a string has m consecutive 1's or 0's
- Length of longest consecutive ones by at most one swap in a Binary String
- Maximum Consecutive Zeroes in Concatenated Binary String
- Maximum length of consecutive 1's in a binary string in Python using Map function
- Check if the string contains consecutive letters and each letter occurs exactly once
- Python | Check if a given string is binary string or not
- Check if all the 1's in a binary string are equidistant or not
- Check divisibility of binary string by 2^k
- Check if it is possible to rearrange a binary string with alternate 0s and 1s
- Check if a binary string has a 0 between 1s or not | Set 1 (General approach)
- Check if a binary string contains all permutations of length k
- Check if a binary string has a 0 between 1s or not | Set 2 (Regular Expression Approach)
- Check if an encoding represents a unique binary string
