EVENFRQ - Even Frequency |
Kutus loves even number. Girl friend of Kutus, name Putus makes an interesting problem for Kutus to testing his even number knowledge. Putus gives an integer array A, consisting of N number.
Putus asked Kutus to process the following three types of queries on this array accurately and efficiently.
- 0 X V: add V to the Xth element of array. i.e. AX = AX + V.
- 1 L R V: replace all the element in range L to R with V.
- 2 L R: Find out whether all elements frequency in the range L to R is/are even or not
Input
Input start with an integer T, which denotes the number of test case. Each case contains 2 space separated integer N and Q denoting the size of array A and the number of queries to be performed.
Next line contains N space separated integers denoting the elements of array A. Each of the next Q lines of input contains a query having one of the mentioned three types. There will be no more than fifty update operation (type 0 and type 1).
Output
For each case print the case number and print the answer. If all elements frequency in the range L to R is/are even, then answer will be ‘Yes’ otherwise answer will be ‘No’.
Constraints
T <= 10
1 <= N <= 100000
1 <= Q <= 100000
0 <= Ai , V <= 100000
1 <= L <= R <= N
Example
Input: 1 5 6 1 2 2 3 2 2 2 3 0 5 1 2 2 5 2 1 5 1 1 3 2 2 1 5 Output: Case 1: Yes Yes No No

I've used some evil technique to successfully "attack" this problem :-) |
