Detect Revisited Coordinates

You are given a list of geographic coordinates expressed as pairs of floating-point numbers representing latitude and longitude. Your task is to determine whether any coordinate appears more than once.

In other words, check if there is any repeated pair in the list. If there is at least one repeated coordinate, output True; otherwise, output False.

Input Format: The input will be given via standard input. The first line contains a non-negative integer \( n \) representing the number of positions. Each of the following \( n \) lines contains two space-separated floating-point numbers representing the latitude and longitude respectively.

Output Format: Output a single line with either True or False indicating whether any coordinate was revisited.

Example:

Input:
4
40.712776 -74.005974
34.052235 -118.243683
40.712776 -74.005974
51.507351 -0.127758
Output:
True

</p>

Note: Coordinates are considered the same if both their latitude and longitude values are exactly equal.

inputFormat

The first line of input contains a single integer \( n \) (\( n \ge 0 \)) indicating the number of coordinates. The next \( n \) lines each contain two space-separated floats representing the latitude and longitude of a coordinate.

outputFormat

Output a single line: True if any coordinate is repeated, otherwise False.
