Problem:
Map: Search

For a dictionary $M$ that stores elements formed by a pair of a string key and an integer value, perform a sequence of the following operations. Note that each key in $M$ must be unique.

insert($key$, $x$): Insert an element formed by a pair of $key$ and $x$ to $M$. If there is an element with $key$, replace the corresponding value with $x$.

get($key$): Print the value with the specified $key$.

Input

The input is given in the following format.

$q$
$query_1$
$query_2$
:
$query_q$

Each query $query_i$ is given by

0 $key$ $x$

or

1 $key$

where the first digits 0, 1 and 2 represent insert and get operations respectively.

Output

For each get operation, print an integer in a line.

Constraints

$1 \leq q \leq 200,000$

$1 \leq x \leq 1,000,000,000$

$1 \leq $ length of $key$ $ \leq 20$

$key$ consits of lower-case letter

For a get operation, the element with the specified key exists in $M$.

Sample Input 1

7
0 blue 4
0 red 1
0 white 5
1 red
1 blue
0 black 8
1 black

Sample Output 1

1

Solution in PHP (judge verdict: Accepted)

<?php
$numbers = fgets(STDIN);
$n = intval($numbers);
// print $n;

$array = [];
for ($i=0; $i < $n; $i++) {
    $numbers = preg_split("/[\s,]+/", rtrim(fgets(STDIN)));
    $o = $numbers[0];
    $p = $numbers[1];
    if ($o == 0){
        $q = $numbers[2];
        $array[$p] = $q;
        // print_r($array);
    } else { // 1の場合
        echo $array[$p];
        echo PHP_EOL;
    }
}
