A program is being designed in pseudocode. The program contains the following declaration for the global array MyData: DECLARE MyData : ARRAY[1:10000] OF STRING A function FindFirst() is written to search the array for a given string and to return the index of the first element where that string is found, or to return -1 if the string is not found. The function is written in pseudocode as shown: FUNCTION FindFirst(SearchString : STRING) RETURNS INTEGER DECLARE Index, FoundAt : INTEGER FoundAt ← -1 FOR Index ← 1 TO 10000 IF MyData [Index] = SearchString THEN // outer conditional clause IF FoundAt = -1 THEN FoundAt ← Index // inner conditional clause ENDIF ENDIF NEXT Index RETURN FoundAt ENDFUNCTION

1. (a)(i)Comment on why the programmer chose –1 as the initial value of FoundAt[1]
2. (a)(ii)Explain the purpose of the outer conditional clause.[1]
3. (a)(iii)The inner conditional clause ensures that only the index of the first matching element, if any, is returned. Explain how this clause works.[1]
4. (b)(i)The pseudocode does not use the most appropriate loop construct. Explain why this is not the most appropriate loop construct.[1]
5. (b)(ii)Suggest and justify a more appropriate loop construct that could be used. Construct Justification[2]
