What is the prefix in rearrangement?
The prefix re-, which means “back” or “again,” appears in hundreds of English vocabulary words, for example: reject, regenerate, and revert. You can remember that the prefix re- means “back” via the word return, or turn “back;” to remember that re- means “again” consider rearrange, or arrange “again.”
What is the prefix in permutations?
A prefix permutation is an index P that satisfies : 0 <= P < N. the sequence A[0], A[1], ..... A[P] is a permutation of integers from 1 to P + 1.
In this paper we introduce an operation, called block-interchange, in which two substrings, or blocks, swap positions in the permutation.
