1. Make a trie of all dictionary words.
2.then run a loop for all characters of string
3.suppose start from I ,as I is a word in dictionary,word found then
increment counter
4.Now counter comes to X,no word found
5.Now it comes to A,two word could start from A(A and AM)
now run this loop till end
Ques Given a large text... in the text.. there are gt; , lt; etc
representing and .(there can be others like eq; etc)
the task is to replace such (gt;) with the '' symbol...
and (lt;) with ''
given the table which have corresponding matches... and
table is
Anagram problem solution using TRIE..
For each word in dictionary we will put it in TRIE as..
1. First sort the word
2. Search in trie using sorted word. If search found then we will add the
original word in that TRIE node.
3. If node node not found then using simple TRIE insertion insert
Ques..
Given a m-word dictionary ... and a n-sized word... .. now suggest DS for
dictionary such that you can find out all the anagrams of the given word
present in dictionary...

@Ashish: According to your algo making multimap itself takes O(mn) time
complexity (preprocessing). After then getting anagram of a string takes
O(n) time. Am i right?

maintain a key.Associate with each word a key.When comparing the string,if
string1string2 swap the keys instead of the words.Saves enormous time.

Is the array sorted?
For Q2 Bitwise X-OR operation of all input numbers does the trick.

2nd part can be done just take the xor of all the numbers same number xor
returns 0 so only seven will remain.
1st part can be done in O(n) because estimate sum - n*(n+1)/2. now sub from
estimated sum each array element. the last value remained is the missing
number.
correct me if i am wrong.
