WebThe split strings are move to branches as shown. Though I am getting LC substrings. But printing the sequence it needs to be presented in binary tree. i.e. print the sequence of the LCS using longest common sub sequence from bottom up . e.g. In 6th level L is on right side of - so the sequence would be - L then it lies on right side of 4th ... Web5 hours ago · Now I want to print the sequence of the LCS using post order traversal. e.g. In bottom 6th level L is on right side of -so the sequence would be - L then it lies on right side of 4th level -hence the Sqence would be - - L. this lies on left side of Maeen hence - - L Maeen and hence adding the right side - - L Maeen - - and so on till root.
