DevOps/SRE Coding Interview Question: 108: Golang: Use Trim &Trimspace Functions from strings pkg

Hey everybody, welcome back! This will be our final video on the string package functions, focusing on `Trim` and `TrimSpace`. If you find this video useful, please like and subscribe—it helps me a lot.

Let's dive into `Trim` and `TrimSpace`. I’m not too familiar with these, so we’ll explore them together. We'll start with the documentation to see what they do.

### Exploring `Trim`
The `Trim` function takes an original string and a cutset string, returning a new string with all leading and trailing Unicode code points contained in the cutset removed. Here's an example to make it clearer:

Imagine you have an original string with characters you want to remove from both ends. By specifying those characters in the cutset, `Trim` will remove them.

### Practical Example
We’ll reuse some code from our last video. Here’s our setup:

You have an original string with extra characters at the beginning and end. By using `Trim` with the appropriate cutset, you can clean up the string effectively.

### Experimenting with `Trim`
Initially, I tried to trim spaces but realized `Trim` only removes characters specified in the cutset. Here’s a corrected example:

When you have spaces you want to remove, specifying them in the cutset will strip them from both ends of the string.

### Using `TrimSpace`
`TrimSpace` is more straightforward as it removes all leading and trailing white spaces. Let's see it in action:

Think of a string with unwanted spaces around it. `TrimSpace` cleans it up by removing all those extra spaces, leaving the core content intact.

### Conclusion
Understanding these functions is crucial, especially for coding interviews where string manipulation is common. Knowing these functions helps you write cleaner, more efficient code without reinventing the wheel.
