# Fibonacci Calculator
A fast and efficient command-line tool written in Rust for calculating large Fibonacci numbers. Supports decimal, scientific notation, and hexadecimal input formats.
## Features
- Computes Fibonacci numbers using an optimized recursive algorithm
- Accepts input in:
- Decimal (e.g., `100`)
- Scientific notation (e.g., `1e2`)
- Hexadecimal (e.g., `0x64`)
- Optional flag to suppress printing the result
- Displays computation time
## Installation
Clone the repository and build it using Cargo:
```bash
git clone https://github.com/Abhrankan-Chakrabarti/fibonacci-calculator.git
cd fibonacci-calculator
cargo build --release
```
## Usage
```bash
cargo run --release -- [OPTIONS]
```
## Options
- --no-print : Suppress printing the Fibonacci result
- --help : Show help message
- --version : Show version information
## Example
```bash
cargo run --release
```
```
This program computes the n-th Fibonacci number.
Enter n : 1e3
