Shaass has decided to hunt some birds. There are n horizontal electricity wires aligned parallel to each other. Wires are numbered1 to n from top to bottom. On each wire there are some oskols sitting next to each other. Oskol is the name of a delicious kind of birds in Shaass's territory. Supposed there area_i oskols sitting on thei-th wire.

Sometimes Shaass shots one of the birds and the bird dies (suppose that this bird sat at thei-th wire). Consequently all the birds on thei-th wire to the left of the dead bird get scared and jump up on the wire numberi - 1, if there exists no upper wire they fly away. Also all the birds to the right of the dead bird jump down on wire numberi + 1, if there exists no such wire they fly away.

Shaass has shot m birds. You're given the initial number of birds on each wire, tell him how many birds are sitting on each wire after the shots.

Input

The first line of the input contains an integer n,(1 ≤ n ≤ 100). The next line contains a list of space-separated integersa₁, a₂, ..., a_n,(0 ≤ a_i ≤ 100).

The third line contains an integer m, (0 ≤ m ≤ 100). Each of the next m lines contains two integersx_i andy_i. The integers mean that for thei-th time Shaass shoot the y_i-th (from left) bird on thex_i-th wire,(1 ≤ x_i ≤ n, 1 ≤ y_i). It's guaranteed there will be at leasty_i birds on thex_i-th wire at that moment.

Output

On the i-th line of the output print the number of birds on thei-th wire.
