D. Welfare State


There is a country with 𝑛n citizens. The 𝑖i-th of them initially has 𝑎𝑖ai money. The government strictly controls the wealth of its citizens. Whenever a citizen makes a purchase or earns some money, they must send a receipt to the social services mentioning the amount of money they currently have.

Sometimes the government makes payouts to the poor: all citizens who have strictly less money than 𝑥x are paid accordingly so that after the payout they have exactly 𝑥x money. In this case the citizens don't send a receipt.

You know the initial wealth of every citizen and the log of all events: receipts and payouts. Restore the amount of money each citizen has after all events.

Input

The first line contains a single integer 𝑛n (1𝑛21051≤n≤2⋅105) — the numer of citizens.

The next line contains 𝑛n integers 𝑎1a1, 𝑎2a2, ..., 𝑎𝑛an (0𝑎𝑖1090≤ai≤109) — the initial balances of citizens.

The next line contains a single integer 𝑞q (1𝑞21051≤q≤2⋅105) — the number of events.

Each of the next 𝑞q lines contains a single event. The events are given in chronological order.

Each event is described as either 1 p x (1𝑝𝑛1≤p≤n, 0𝑥1090≤x≤109), or 2 x (0𝑥1090≤x≤109). In the first case we have a receipt that the balance of the 𝑝p-th person becomes equal to 𝑥x. In the second case we have a payoff with parameter 𝑥x.

Output

Print 𝑛n integers — the balances of all citizens after all events.

Note

In the first example the balances change as follows: 1 2 3 4 → 3 3 3 4 → 3 2 3 4 → 3 2 3 4

In the second example the balances change as follows: 3 50 2 1 10 → 3 0 2 1 10 → 8 8 8 8 10 → 8 8 20 8 10
