Both of these methods will require extra ,memory On Wed, Aug 24, 2011 at 9:42 PM, Anup Ghatage ghat...@gmail.com wrote: How about this, We compare the first character with every character except the characters in the word itself, if there is a hit, it might be a word which is a duplicate. So from there on, compare each of the following characters till there is a white space or new line character. If there is no match, skip all the next characters and start with the next word's first character, but search only from that index to n. if there is a complete match, shift all the characters following the duplicate to the duplicates position.

Do you mean even O(1) isn't good? On Wed, Aug 24, 2011 at 8:43 PM, UMESH KUMAR kumar.umesh...@gmail.com wrote: Qn. Remove all duplicates words from given a line without using extra memory ?
