2. If count[x] is 1, then store index of x in index[x], i.e., index[x] = i.
3. If count[x] is 2, then remove x from index[], i.e., index[x] = n.

How to make a binary string an alternate string?

Given a binary string, the task is to find minimum number of characters to be removed from it so that it becomes alternate. A binary string is alternate if there are no two consecutive 0s or 1s. Examples : Input : s = “000111” Output : 4 We need to delete two 0s and two 1s to make string alternate.

How to transform one string to another in DP?

Construct a 2D DP matrix of m*n size, where m is size of string B and n is size of string A. dp [i] [j] gives the number of ways of transforming string A [0…j] to B [0…i]. Case 1 : dp [0] [j] = 1, since placing B = “” with any substring of A would have only 1 solution which is to delete all characters in A.
