题目描述
You have a malfunctioning microwave in which you want to put some bananas. You have n time-steps before the microwave stops working completely. At each time-step, it displays a new operation.
Let k be the number of bananas in the microwave currently. Initially, k=0 . In the i -th operation, you are given three parameters ti , xi , yi in the input. Based on the value of ti , you must do one of the following:
Type 1: ( ti=1 , xi , yi ) — pick an ai , such that 0≤ai≤yi , and perform the following update ai times: k:=⌈(k+xi)⌉ .
Type 2: ( ti=2 , xi , yi ) — pick an ai , such that 0≤ai≤yi , and perform the following update ai times: k:=⌈(k⋅xi)⌉ .
Note that xi can be a fractional value. See input format for more details. Also, ⌈x⌉ is the smallest integer ≥x .
At the i -th time-step, you must apply the i -th operation exactly once.
For each j such that 1≤j≤m , output the earliest time-step at which you can create exactly j bananas. If you cannot create exactly j bananas, output −1 .
输入格式
The first line contains two space-separated integers n (1≤n≤200) and m (2≤m≤105) .
Then, n lines follow, where the i -th line denotes the operation for the i -th timestep. Each such line contains three space-separated integers ti , xi′ and yi ( 1≤ti≤2 , 1≤yi≤m ).
Note that you are given xi′ , which is 105⋅xi . Thus, to obtain xi , use the formula xi=105xi′ .
For type 1 operations, 1≤xi′≤105⋅m , and for type 2 operations, 105<xi′≤105⋅m .
输出格式
Print m integers, where the i -th integer is the earliest time-step when you can obtain exactly i bananas (or −1 if it is impossible).

说明/提示
In the first sample input, let us see how to create 16 number of bananas in three timesteps. Initially, k=0 .
- In timestep 1, we choose a1=2 , so we apply the type 1 update — k:=⌈(k+3)⌉ — two times. Hence, k is now 6.
- In timestep 2, we choose a2=0 , hence value of k remains unchanged.
- In timestep 3, we choose a3=1 , so we are applying the type 1 update k:=⌈(k+10)⌉ once. Hence, k is now 16.
It can be shown that k=16 cannot be reached in fewer than three timesteps with the given operations.
In the second sample input, let us see how to create 17 number of bananas in two timesteps. Initially, k=0 .
- In timestep 1, we choose a1=1 , so we apply the type 1 update — k:=⌈(k+3.99999)⌉ — once. Hence, k is now 4.
- In timestep 2, we choose a2=1 , so we apply the type 2 update — k:=⌈(k⋅4.12345)⌉ — once. Hence, k is now 17.
It can be shown that k=17 cannot be reached in fewer than two timesteps with the given operations.
