4 Study the following pseudocode. Line numbers are for reference only. 10 FUNCTION Convert(Name : STRING) RETURNS STRING 11 12 DECLARE Flag: BOOLEAN 13 DECLARE Index : INTEGER 14 DECLARE ThisChar : CHAR 15 DECLARE NewName : STRING 16 17 CONSTANT SPACECHAR = ' ' 18 19 Flag ← TRUE 20 Index ← 1 21 NewName ← "" // formatted name string 22 23 WHILE Index <= LENGTH(Name) 24 ThisChar ← MID(Name, Index, 1) 25 IF Flag = TRUE THEN 26 NewName ← NewName & UCASE(ThisChar) 27 IF ThisChar <> SPACECHAR THEN 28 Flag ← FALSE 29 ENDIF 30 ELSE 31 NewName ← NewName & ThisChar 32 ENDIF 33 IF ThisChar = SPACECHAR THEN 34 Flag ← TRUE 35 ENDIF 36 Index ← Index + 1 37 ENDWHILE 38 39 RETURN NewName 40 41 ENDFUNCTION (a) Complete the trace table below by dry running the function when it is called as follows: Result ← Convert("VinVa∇∇Cup") Note: The symbol 'V' has been used to represent a space character. Use this symbol for any space characters in the trace table. The first row has been completed for you. Name | Flag | Index | NewName | ThisChar --------------|------|-------|---------|--------- "VinVa∇∇Cup" | | | | (b) The pseudocode for Convert() contains a conditional loop. State a more appropriate loop structure. Justify your answer.

Justification ....................................................................................................................................................... (c) Two changes need to be made to the algorithm. Change 1: Convert to lower case any character that is not the first character after a space. Change 2: Replace multiple spaces with a single space. (i) Change 1 may be implemented by modifying one line of the pseudocode. Write the modified line. (ii) Change 2 may be implemented by moving one line of the pseudocode. Write the number of the line to be moved and state its new position.
