`\mod` | ~1 \mod 2~ | Should be rarely used. |

`\bmod` | ~1 \bmod 2~ | Should be commonly used. |

`\pmod` | ~1 \pmod 2~ | Should be used normally. |

`\text{ mod }` | ~1 \text{ mod } 2~ | Bulky, should be used as a last resort. Looks identical to `\bmod` in this case. |

## Input Specification
A description of the input format goes here.
The first line of the input will contain an integer ~N~, representing the number of elements in array ~A~.
The next ~N~ lines will each contain an element ~a_i~ ~(1 \le i \le N)~, denoting the elements of array ~A~.
## Constraints
A description of the bounds of all defined variables goes here.
**Note:** This is optional, and usually reserved for problems with subtasks.
For all subtasks:
~1 \le a_i \le 100~
### Subtask 1 [20%]
~1 \le N \le 20~
### Subtask 2 [30%]
~1 \le N \le 1\,000~
### Subtask 3 [50%]
~1 \le N \le 10^5~
Alternatively, you may use a table to communicate details in bulk:

Subtask | Marks | ~N~ |
---|---|---|

~1~ | ~20\%~ | ~1 \le N \le 20~ |

~2~ | ~30\%~ | ~1 \le N \le 1\,000~ |

~3~ | ~50\%~ | ~1 \le N \le 10^{5}~ |
