variable length records and binary search?
817773
a  binary search works on the principle of the left node being smaller than the central node and the right node being larger than the central node..assuming the node i am searching for has the value 5 and the central node 2 levels up is 10\n\nso 10 can have two child nodes right node =14,left node =7\n7 can have two nodes =left node 5,right node 9\n\n\nwhat an index on a record file of variable length would do is assign a unique id to each record in that file,so when the binary search is going on to find a specific node,it will have to follow the lesser path or greater than central node path..so to find the lesser part it will have to determine the position of the next node ..this is done by indexing since all it has to do is to reference that unique id which will point it to the next node and so on...\n\n\nIf the records are not indexed it will not be able to determine which node exists hence will fail

Generally the idea is:\n\nDo Until Decimal = 0\n    If (Decimal Mod 2) Then\n        Let Binary = "1" & Binary\n    Else\n        Let Binary = "0" & Binary \n    End If\n    Let Decimal = Decimal &#92; 2\nLoop\n\n(Decimal is a number, Binary is a string variable)

If you are thinking of f : ? -> { 0, 1, 2, 3, ... } (i.e., the domain is mapped into the set of non-negative integers) then clearly the domain "?" contains [at least] all finite bit strings.  If you keep the same restriction on the range, you can even extend the domain to include those infinite bit strings (however you wish to define that) which contain only finitely many ones.  If you extend the range to also include infinite cardinals and/or ordinals then you can include even more infinite bit strings into the domain.

In binary, the first line of a 'flat file' is not the one you want to use as a template for the rest of the file. It is likely to be header information for the file as opposed to data in the file. Most tools, which extract the information you need, will discard or interpret the first line as 'file header'. Information in the first line usually includes the length of the header, the length of the file, the length of the 'record', the number of records, etc. The tools which interpret the first line may need assistance in defining the fields. The tools which discard the first line will assume some form of delimiter is present to provide your information.\nMost of the 'flat files' with which I have worked have no delimiter. This means I have to determine the record length and field length parameters for the tool to utilize by looking at a binary listing. This process can be particularly complex when the record length is variable.\nAs to which tool, it depends on what you have available. At times, I have written my own tool to manipulate a given flat file. \n\nIf you have MS Excel, MS Excel can ‘Import’ your flat file by using the delimiters already present in the flat file or use a wizard-generated template you help design.\n\nI have used several ‘mainframe utilities’ for this purpose.\n\nSome programming language editors can provide a binary/character look at the flat file.\n\nIt helps a great deal to have some idea of how the various fields are used in the file.

Try tracing a very small example on paper to gain some insight into this.  Perhaps just two or three elements with at least two equal keys.  Then reverse the order of the two equal keys in the input set, and see if you still get the same result.  Tracing the algorithm like this will get you the answer in a manner that should give you some confidence.

Your problem here is that your records are empty. You should be something like this:\n\ndata1.recordset.movefirst\ndo while not data1.recordset.eof\n  code to do whatever on the data in the recordset\n  data1.recordset.movenext\nloop\n\nor if you are trying to evaluate only one record:\n\nIf data1.recordset.eof = false then\n  code to do whatever on the data in the recordset\nElse\n  code to do whatever if the recordset doesn't exist\nEnd If

Ah, love these kinds of problems.\n\nOK, there is a very efficient solution if you restrict yourself to integer types. Try this code:\n\nint Answer = 0;\nint i;\nfor (i=0; i < 2*n + 1; i++)\n{\n   Answer ^= Array[i];\n}\nprintf ("Single entry is %d&#92;n", Answer);\n\nThe clincher here is that every integer when exclusive ORed with itself yields zero, so all of the duplicates simply disappear - you will only be left with the unpaired entry.

you can't really "catch" them per se, as they are really not errors, unlike floating point overflows. \nYou can do some sanity checks like the above answer explained...\nor better, just use larger storage - like unsigned long long - that'll give you more space without overflowing.

Use sprintf(), it allows you to "print" into an array.\n\nint x = 123;\nchar temp[10];\nsprintf(temp, "%d", x); // temp will contain "123"\n\nJust make sure that buffer is large enough to hold all the digits of your largest number + 1 for the null terminator.

You use limit in conjunction with 1 or 2 numbers. If you use 1 number like this:\n\nselect * from myTable limit 5;\n\nthen MySQL will grab the first 5 results from the table. However, if you use if like this:\n\nselect * from myTable limit 5,5;\n\nthen MySQL will grab 5 results, starting from record number 5. So it's\n\nlimit [startPos], [numberOfRecords]\n\nEnjoy -

Okay once again..\nStringBuffer b = buf.replace(6,10,"orld");\n\nThis replaces offset 6 to 10 with world... So offset 6 in your case is W so it would be:\nHello orld\n\nNow That is correct.. Now b.delete(0, 1)\nThat deletes the 0 offset which is H! only so it would be\nello\n\nNow the total StringBuffer Contents is:\nello orld\n\n\nSee why? Remember buffers is like a memory location that stores a buffer, so treat it as global scope in that case

Not completely sure I follow the question.  But if you are trying to store parameters, repeating units, etc.. I would recommend a generic "code" table that can house multiple types of values.  You could have a table with a Type, subtype, values and description that could hold all kinds of values.  \n\nType: Construction\nSubType: tool\nValue: hammer\nDesc: tool to pound on things\n\nnext record\nType: Construction\nSubType: measurement\nValue: inches\nDesc: english measurement\n\nnext record\nType: Construction\nSubType: measurement\nValue: centimeters\nDesc: metric measurement\n\nnext record\nType: Query\nSubType: Parameter\nValue: RunDate\nDesc: Time surrounding query execution\n\n\nAnd so on and so on.....\n\nselect * from code_table where Type = 'Construction'\nand SubType = 'measurement'\n\nIt is easy to replicate, extend and edit.\n\nGood Luck in pursuing your answers.

Look up "quicksort".\n\nIt fits very naturally into a recursive implementation\nand is also a very efficient sorting algorithm.\n\nI've included a link to the Solaris source for quicksort.\nIt is written in C (rather than C++).  It is somewhat\ncomplicated because it optimizes the sorting of\nshort sequences by switching to an insertion sort.\nHowever, you could implement a simpler version which\nran quicksort all the way to completion.

Binary search is a common searching algorithm used in searching for values in a list of values. Its can be implemented by any programming language not just C++.\n\nhttp://en.wikipedia.org/wiki/Binary_search\n\nThis should give you a better explaination of it.
