Read string in revers

tsureshinvites — Thu, 16 Jan 2020 02:48:49 GMT

Hi,

Please assist me to write algorithm for the below task.

Input raw data:

String = "Suresh Kumar thangaraj"

Output required:

New_String = "hseruS ramuK jaragnaht"

But my output;

My output;

"jaragnaht ramuK hseruS";

My Code:

data test;
length New_string $30;
string = "Suresh Kumar thangaraj";
L = length(string);
do i = 1 to L;
substr(New_string,i,1) = substr(string,L+1-i,1);
end;
run;

Regards,

Suresh Kumar

YOU want to keep word order, but reverse all the letters in each word.

YOu need to know:

How many words are in STRING (take a look at the COUNTW function).
How to loop over each word one at a time (consider DO W=1 to number_of_words_in_STRING).
How to extract one word at a time from STRING (look at the SCAN function)
How to reverse a sequence of text in the word (look at the REVERSE function)
How to concatenate (with space separation) each reversed word, one at a time into NEW_STRING (look at the CATX function).

It's all about the journey.
