# If and else statement ## Example Execute the following command to run [`./solutions/examples/if_else.rs`](https://github.com/Cyfrin/rust-crash-course/blob/main/topics/if_else/solutions/examples/if_else.rs) ```shell cargo run --example if_else ``` ## Exercises Exercises are in [`./exercises/src/lib.rs`](https://github.com/Cyfrin/rust-crash-course/blob/main/topics/if_else/exercises/src/lib.rs) ### Exercise 1 ```rust pub fn min(x: i32, y: i32) -> i32 { todo!(); } ``` Return the minimum of `x` and `y`. ### Exercise 2 ```rust pub fn max(x: i32, y: i32) -> i32 { todo!(); } ``` Return the maximum of `x` and `y`. ### Exercise 3 ```rust pub fn sign(x: i32) -> i32 { todo!(); } ``` Return the sign of `x`. If `x` is negative, return -1, otherwise return 1. ## Test ```shell cargo test ```
