Squares of Positive Integers

You are given a list of integers. Your task is to filter out the non-positive integers and calculate the square of each positive integer. Then, output the result as a dictionary (or map) where each key is the positive integer and the corresponding value is its square. The keys in the output must be sorted in ascending order.

Note: The dictionary should be printed in the following format: {key1: value1, key2: value2, ...}. If there are no positive integers, output {}.

Example:

Input:
3
1 2 3
Output:
{1: 1, 2: 4, 3: 9}

The squaring operation is given by the formula: \( n^2 \), where \( n \) is a positive integer.

inputFormat

The first line contains an integer ( n ) denoting the number of integers. The second line contains ( n ) space-separated integers.

outputFormat

Output a dictionary where each positive integer from the input is a key and its value is the square of the integer. The keys must be printed in ascending order. For example, if the input is:

3 1 2 3

then the output should be:

{1: 1, 2: 4, 3: 9}## sample

3
1 2 3

{1: 1, 2: 4, 3: 9}
