Words Manupulation in a String

[BrahmanandaRao]

HI Good Morning 

I wan to below output is 

OUTPUT:

data test;
x='sas is the leader in analytics';
put x;
run;

SaS iS tHE lEaDeR iN aNaLyTiCs

Not sure why you'd want to do this but LENGTH() will give you the length of the string, CHAR() with an index will give you the specific character and you can change the case using UPCASE()/LOWCASE() to change the case.

You need a do loop to loop over the characters.

You're assuming your interviewer can't see this page by the way.

data test;
format x $50.;
x='sas is the leader in analytics';
do i=1 to length(x);
	if mod(i,2)>0 then substr(x,i,1)= upcase(substr(x,i,1));
end;
run;

Hi Unison

Thank you very much  brilliant code 

[ChrisNZ]

Sightly simpler:

if mod(I,2) then substr(X,I,1)= upcase(char(X,I));

Here is one way:

data test;
  length word $20.;
  length y $80.;
  x='sas is the leader in analytics';
  n=1;
  do until (missing(scan(x,n)));
    word=scan(x,n);
    if not missing(word) then do;
      if n eq 1 then do;
        substr(word,1,1) = upcase(substr(word,1,1));
        substr(word,3,1) = upcase(substr(word,3,1));
      end;
      else if n eq 3 then do;
      substr(word,2,1) = upcase(substr(word,2,1));
      substr(word,3,1) = upcase(substr(word,3,1));
      end;
      else do i=2 to length(word) by 2;
        substr(word,i,1) = upcase(substr(word,i,1));
      end;
      put word;
      y=catx(' ',y,word);
      n+1;
    end;
  end;
  put x;
  put y;
run;

Than You sir support 

your coding skills are par excellence

[SASKiwi]

Just my two cents worth - I personally can't see the point of interview questions about things you would never do in a real job. If you want to test a candidate's string manipulation skills then choose real-life examples like names, addresses, job descriptions etc.

[Reeza]

Maybe, This is a decent question to test if a candidate has the skills they claim. It's basic enough that most programmers should understand it and it's quick without having to ask many questions. This is something a beginner SAS programmer should be able to answer in less than 30 minutes. Some orgs have limits on what we can test - my current one only allows me an hour, where the previous role I used to ask for a take home test that was definitely time intensive.

data test;
x='sas is the leader in analytics';
y=prxchange('s/(.)(.)/\u\1\2/',-1,x);
run;

[art297]

You will fail the question if you provide the response you chose as correct. Carefully compare the test phrase with the output from each suggestion.

Hello,

In your example, H and E in "tHE" are both upper case. I guess this is a mistake and so is the remainder of

the example string.

data test;
    x='sas is the leader in analytics';

    upcase_this=1;

    do i=1 to length(x);
        if anyalpha(substr(x,i))=1 then do;
            if upcase_this then substr(x,i,1)=upcase(substr(x,i,1));
            upcase_this=1-upcase_this;
        end;
    end;
    put x;
run;

My first response would be: What are the actual RULES involved in the manipulation? One single literal example => Type the desired response. Why bother attempting to GUESS an algorithm without rules to implement?

Example deduce the rule behind:

1   => 3

2   => 3

3   => 5

4   => 4

5   => 4

So what would be the result for 6, 7 and 8?
