How to trim white spaces from the slice of bytes in Golang?
In Go language slice is more powerful, flexible, convenient than an array, and is a lightweight data structure. The slice is a variable-length sequence which stores elements of a similar type, you are not allowed to store different type of elements in the same slice.
In the Go slice of bytes, you are allowed to trim all the leading and trailing white space from the given slice using TrimSpace() function. This function returns a subslice of the original slice by removing off all leading and trailing white space. It is defined under the bytes package so, you have to import bytes package in your program for accessing TrimSpace function.
func TrimSpace(ori_slice byte) byte
Here, ori_slice is the original slice of bytes. Let us discuss this concept with the help of the given examples:
Original Slice: Slice 1: !!GeeksforGeeks## Slice 2: **Apple^^ Slice 3: %geeks% New Slice: Slice 1: !!GeeksforGeeks## Slice 2: **Apple^^ Slice 3: %geeks%
Final Slice: Slice 1: ****Welcome to GeeksforGeeks**** Slice 2: !!!!Learning how to trim a slice of bytes@@@@ Slice 3: Geek, GeeksforGeeks
