D. Welfare State
There is a country with n citizens. The i-th of them initially has ai 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 x are paid accordingly so that after the payout they have exactly x 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.
The first line contains a single integer n (1≤≤2⋅1051≤n≤2⋅105) — the numer of citizens.
The next line contains n integers 1a1, 2a2, ..., an (0≤≤1090≤ai≤109) — the initial balances of citizens.
The next line contains a single integer q (1≤≤2⋅1051≤q≤2⋅105) — the number of events.
Each of the next q lines contains a single event. The events are given in chronological order.
Each event is described as either 1 p x (1≤≤1≤p≤n, 0≤≤1090≤x≤109), or 2 x (0≤≤1090≤x≤109). In the first case we have a receipt that the balance of the p-th person becomes equal to x. In the second case we have a payoff with parameter x.
Print n integers — the balances of all citizens after all events.

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
