Three-dimensional hybrid implicit–explicit
Abstract: A novel hybrid <em>implicit</em>–explicit (HIE) finite-difference time-domain (FDTD) method, which is extremely useful for problems with very fine structures along the w-direction in cylindrical coordinate system, is presented. This method has higher computation efficiency than conventional cylindrical FDTD methods, because the time step in this method is only determined by the space discretisations in the radial and vertical directions. The numerical stability of the proposed HIE–FDTD method is presented analytically. Compared with the cylindrical alternating-direction <em>implicit</em> (ADI)–FDTD method, this HIE–FDTD method has higher accuracy, especially for larger time step size. At each time step, the HIE–FDTD method requires the solution of two tridiagonal matrices and four explicit updates. While maintaining the same size of time step, the central processing unit (CPU) time for this weakly conditionally stable FDTD method can be reduced to about 3/5 of that for the ADI–FDTD scheme. The numerical performance of the proposed HIE–FDTD over the conventional cylindrical FDTD method and cylindrical ADI–FDTD method is demonstrated through numerical examples.

Dynamic Declaration Language (DDL)
DDL is a very simple programming language in which variables are dynamically declared at run time. All variables in DDL are of the signed integer type within the range -9999...9999. There are up to five types of statements in a DDL program (each statement is in a separate program line, and the first statement is in line 1):n1. Dcl nDcl is a keyword specifying a <em>declaration</em> statement. id is a single (case-sensitive) letter designating a DDL variable. For example Dcl x when executed correctly, allocates memory for variable x, and sets its value to zero.nn2. = nThis is an assignment statement, where id is a DDL variable, and ic is a literal integer constant in the range (0...9999). For example x = 2000 when executed correctly, changes value of x to 2000. Note that there may be one or more number of blank characters around =, but there is no tab characters.nn3. Goto , or Goto nGoto is a keyword specifying an unconditional or conditional goto statement. label is a program line's number. For example Goto 5 transfers the program execution flow to line 5 of the program, and nGoto x 5 when executed correctly, trasfers the flow to line 5 iff x>0, and to the next line otherwise. The label is guaranteed to be in the range of program line numbers.nn4.Inc , or Dec nInc and Dec are keywords specifying increment and decrement statements respectively. For example Inc x (Dec y) when executed correctly adds (substracts) 1 to (from) the value of x (y).nn5. EndnEnd is a keyword specifying the end statement, whose execution stops the program.nnNot that the keywords of the DDL language are case-insensitive.nnError conditions:nnWhen one of the following erroneous statements encounters during the program execution, an error message appears in a separate line of the output. Each error message is of the form . label is the line number for the erroneous statement, space is one blank character, and error code is a positive integer specified below.nn1. Dcl x is erroneous if x has not been referenced (used in assignment, goto, increment or decrement) since the last time a Dcl x (declaring the same variable) statement has been executed, unless this is the first Dcl x statement being executed. In this erroneous condition, an error message indicating a repeated <em>declaration</em> is generated as 1, where label is the program line number for the erroneous statement. Then the program flow transfers to the statement in the next program line, and any prior correctly executed <em>declaration</em> for x is valid.nn2.Any other statement where a variable such as x is referenced (used in assignment, goto, increment or decrement) is erroneous if no Dcl x has been previously correctly executed. In this case, an error message indicating an undeclared reference is generated as 2 and the program execution continues from the next line.nnnInputnnFirst line of the input file contains a single integer N indicating the number of DDL programs to follow (1 <= 20). The first line of each test case contains a single integer indicating number of statements in that program which is in the range (1...100). There are no blank lines between test cases. Statements of each DDL program come one after the other in separate lines without any blank lines in between. Statements are not explicitly labeled, but they are <em>implicit</em>ly labeled by the number of their line beginning from 1 for the first statement in each program. There is no syntax error in programs and they are guaranteed to terminate, and no overflow or underflow errors will occur during execution. In each line of the program, tokens (e.g. GOTO, =, etc.) are separated by at least one blank character. Also there may be some blank characters in the beginning or at the end of each line.nnnOutputnnFor each input DDL program, your output should start with the program number in the first line, followed by the error messages generated by the program in the order they are generated, each error message in one line. There should be no blank lines between error messages.nnnSample Inputnn2n4nDCL XnINC XnDCL XnENDn9nDCL XnINC XnGOTO X 5nDCL YnY = 100nDCL XnDCL XnY = 50nENDnnnSample Outputnn1n2n5 2n7 1n8 2
