[Submit] [Status] [Discuss] Description has recently learned a magical magic that can make a person grow taller. So he was ready to demonstrate to each hero of the Xmyz Information Group. So NHeroes gathered together again, this time they lined up in a row numbered 1, 2 、......、 N。 Each person's height begins with a positive integer that does not exceed 1000. The magic of the bishop can turn the closed interval [ L, R] (1≤ L≤ R≤ NThe height of the hero in all plus an integer W。 (Although L= RNot conform to the written specification of the interval, but we may consider it a separate addition to the L（ RThe height of a hero) CYZ, Brother Guang and ZJQ are not religious, so they sometimes ask the WD closed zone [ L, R] Inside how many heroes are taller than equals CTo verify that the magic of the Guru is really effective. WD was lazy, so he gave you the task of answering. Input 1th Behavior two integers N、 Q。 QSum of the number of questions and the number of spells cast by the Guru. Line 2nd has NA positive integer, section INumber represents the first IThe height of a hero. 3rd to No. Q+2 rows have one operation per line: (1) If the first letter is "M", then there are three digits L、 R、 W。 Indicates the closed interval [ L, R] All the hero's height plus W。 (2) If the first letter is "A", then there are three digits L、 R、 C。 Ask the closed interval [ L, R] How many heroes are taller than equals in height C。 Output for each "a" query outputs a line with only one integer, indicating the closed interval [ L, R] inside height is greater than or equal to CNumber of Heroes.

"Input and Output sample description"
The original 5 heroes were 1, 2, 3, 4, 5, and at this time [1, 5] There were 2 heroes taller than or equal to 4. The master cast to 1, 2, 4, 5, 6, at this time [1, 5] There are 3 heroes taller than or equal to 4.

"Data Range"
For 30% of the data, N≤1000, Q≤1000.
For 100% of the data, N≤1000000, Q≤3000,1≤ W≤1000,1≤ C≤1,000,000,000.
