The second line contains n integers aI, which indicates the initial pleasure value of the first flower.
The third line contains an integer m, which means Qiushi sings the song of M-day.
NextM row with three integers per linel R V, indicating that Qiushi to the flowers in theinterval [l,R], the pleasure value of each flower increased by v.
1≤N,M,AI,|v| ≤100000,1 ≤l≤r≤n< Span id= "mjxp-span-65" class= "Mjxp-mo". /span>
