Given a string consisting only of 1’s and 0’s. In one flip we can change any continuous sequence of this string. Find this minimum number of flips so the string consist of same characters only.
Input : 00011110001110 Output : 2 We need to convert 1's sequence so string consist of all 0's. Input : 010101100011 Output : 4
We need to find the min flips in string so all characters are equal. All we have to find numbers of sequence which consisting of 0’s or 1’s only. Then number of flips required will be half of this number as we can change all 0’s or all 1’s.
Time Complexity: O(n)
