Given two strings A and B consisting of only lowercase letters, the task is to find the minimum number of subsequences required from A to form B.
Input: A = “abbace” B = “acebbaae”
Sub-sequences “ace”, “bba”, “ae” from string A used to form string B
Input: A = “abc” B = “cbacbacba”
- Maintain an array for each character of A which will store its indexes in increasing order.
- Traverse through each element of B and increase the counter whenever there is a need for new subsequence.
- Maintain a variable minIndex which will show that elements greater than this index can be taken in current subsequence otherwise increase the counter and update the minIndex to -1.
Below is the implementation of the above approach.
