Cracking The Coding Interview |URLify The Given String | Competitive Programming | Array Problem

line 13 : index should be compared with str.length line 14: should be str[index] = '\0'; i.e if the "index" calculated is less than the original string "str" then that means, str has extra spaces so to avoid those extra spaces in the final result we add null char at "index" position.

Thanks for explanation. I think the author just copy code in the book. I'm reading the 6th edition of the book and was confused by those 2 lines

[@dinosaurperson2349]

I cant understand why its str[index-1] rather than just str[index] which would make the others str[index-1] and str[index -2]

[@neghatnazir1668]

thanks again :), can you pls tell me what is true length here? length of given string with all the whitespaces in between and end ? or length of string from from 0 to last char?

[@pawansnair997]

"Mr John Smith " True length for this is 13

Done mil gaya

I think, instead of str[trueLength] = '\0' it should be str[index] = '/0'. NO?

This line is totally unnecessary in Java, seems like he just copy-pasted the solution from the book. And for C/C++ it should be str[index]
