How to split a 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 split the given slice using a Split() function. This function splits a slice of bytes into all subslices separated by the given separator and returns a slice which contains all these subslices. It is defined under the bytes package so, you have to import bytes package in your program for accessing Split function.
func Split(o_slice, sep byte) byte
Here, o_slice is the slice of bytes and sep is the separator. If the sep is empty, then it will split after each UTF-8 sequence. Let us discuss this concept with the help of the given examples:
Original Slice: Slice 1: !!GeeksforGeeks## Slice 2: Apple Slice 3: %g%e%e%k%s% After splitting: Slice 1: [!!G sforG s##] Slice 2: [A p p l e] Slice 3: [ g e e k s ]
Final Value: Slice 1: [****Welcome to GeeksforGeeks****] Slice 2: [Learning how to trim a slice of bytes] Slice 3: [G e e k s f o r G e e k s , G e e k] Slice 4:
