You are a denizen of Linetopia,who n major cities happen to be equally spaced along an east-west line.In fact,they are often numbered in order from 1 to n,where 1 is the westmost city and n is the eastmost city.
Linetopia was a lovely place to live until forces from neighboring Trapez invaded.As part of Linetopia’s Shielding Lives and Protecting Citizens initiative,you have been called upon to process information about Trapezoid troop movements so we can determine which cities have been hardest hit and know where to nd reinforcements.
Linetopia intelligence has discovered that the Trapezoid forces are attacking in the following pattern.They are nding massive aircraft to drop troops on Linetopia cities.Each aircraft starts at some city i,dropping s soldiers.The aircraft then proceeds tofly either east or west.Each time itflies over another city,it drops a more soldiers than it dropped on the previous city it pasd.After performing d drops,the aircraft returns to Trapez to resupply.
You will be receiving intel updates that inform you of the specs of each Trapezoid aircraft passing over Linetopia.You want to answer queries that ask how many Trapezoid troops have been dropped on a particular city.Are you up to the task?

The first line of input contains a single integer T(1≤T≤10),the number of test cas.The first line of each test ca contains two integers:m(1≤m≤10,000),the number of updates and queries and n(1≤n≤500,000),the number of cities in Linetopia.
The next m lines of input are either updates or queries.Update lines begin with a capital U,then contain either a capital E(east)or W(west)to indicate direction,and then contain four integers i(1≤i≤n),s(1≤s≤10,000),a(0≤a≤10,000),and d(1≤d≤n).The integers signify the starting city,the starting number of soldiers,the increa in soldiers per city,and the number of drops,respectively.You can assume d never results in an aircraft flying to the west of city 1 or to the east of city n.打虎上山简谱>发酵技术
