Given an integer N which shows the size of the string and in the next line given a string which contain string of character with only zero and one. Task is to remove single character each time which comes in between the two zero character.
During each turn, only one character from the string will be removed that satisfies the following condition :
- It must be surrounded by zeroes on both sides.
Input : str = "1001 Output : str = "1001" Input : str = "10101 Output : str = "1001"
Use a loop from 1 to N – 1 and check if any element lies between two zeros such that s[i – 1] = ‘0’ and s[i + 1] = ‘0’. If the condition is satisfied then, delete the character at that position, ad start searching for pattern again.
Time Complexity : O(N), where N is the size of input string.
