GIVEAWAY  Give Away
You are given a 1indexed array X, consisting of N integers, and a set of Q queries. There are two kinds of queries:
 0 a b c
Here you are required to return the number of elements with indices in [a,b]
greater than or equal to c  1 a b
Here you are required to change the a^{th} element of array to b.
Input Format:
First line contains N, the number of elements in the array X. The next line contains N space separated integers representing the elements of X. The third line of input contains a single integer, Q, the number of queries. The next Q lines of input each contain queries of two kinds as described above.
Output Format:
Q lines with the ith line contains the answer for the i^{th} query
Constraints:
1 ≤ N ≤ 5*10^5
1 ≤ Q ≤ 10^5
1 ≤ X[i] ≤ 10^9
1 ≤ a ≤ b ≤ N for query type 0
1 ≤ a ≤ 10^5, 1 < b ≤ 10^9 for query type 1
1 ≤ c ≤ 10^9
Example
Sample Input: 5 1 2 3 4 5 3 0 1 5 10 1 2 20 0 1 3 10 Sample Output: 0 1

I am using segment tree+AVL tree and O(log^2N) for query and O(logN) for update. But its giving TLE on 10th test case. And also it got accepted on codechef. Last edit: 20160102 10:54:15
