CS计算机代考程序代写 DNA /*

/*
* DNA sequence characters {‘A’,’C’,’G’,’T’} are indexed by {0, 1, 2, 3} respectively.
*
* The Replace costs are defined in replaceMatrix.
* For example, replaceMatrix[1][0] is the cost when ‘C’ is replaced by ‘A’.
* 1 represent ‘C’, 0 represent ‘A’, C->A
*
* The Insert costs are defined in insertMatrix.
* For example, insertMatrix[1] is the cost when ‘C’ is inserted.
*
* The Delete costs are defined in deleteMatrix.
* For example, deleteMatrix[1] is the cost when ‘C’ is deleted.
