How to get all the possible K length Substrings in a String in Kotlin ?

Answer

To get all possible K length substrings in a string in Kotlin, you can use a loop to iterate through the string and extract substrings of length K.

✐ Examples

1 Get All K=3 Length Substrings from String "abcdefg"

In this example,

We create a string named str with a value.
We define an integer variable k that specifies the length of the substrings we want to extract.
We initialize an empty mutable list named substrings to store the substrings.
We use a for loop to iterate through the string, stopping at a position where a substring of length k can still be extracted.
Inside the loop, we use the substring method of the string object str to extract a substring of length k starting at the current index i.
We add the extracted substring to the substrings list.
After the loop, we print each substring in the substrings list.

Kotlin Program

fun main(args: Array<String>) {
    val str = "abcdefg"
    val k = 3
    val substrings = mutableListOf<String>()
    for (i in 0..str.length - k) {
        substrings.add(str.substring(i, i + k))
    }
    for (substring in substrings) {
        println(substring)
    }
}

Output

abc
bcd
cde
def
efg

2 Get All K=4 Length Substrings from String "hello world"

In this example,

We create a string named str with a different value.
We define an integer variable k that specifies the length of the substrings we want to extract.
We initialize an empty mutable list named substrings to store the substrings.
We use a for loop to iterate through the string, stopping at a position where a substring of length k can still be extracted.
Inside the loop, we use the substring method of the string object str to extract a substring of length k starting at the current index i.
We add the extracted substring to the substrings list.
After the loop, we print each substring in the substrings list.

Kotlin Program

fun main(args: Array<String>) {
    val str = "hello world"
    val k = 4
    val substrings = mutableListOf<String>()
    for (i in 0..str.length - k) {
        substrings.add(str.substring(i, i + k))
    }
    for (substring in substrings) {
        println(substring)
    }
}

Output

hell
ello
llo 
lo w
o wo
 wor
worl
orld
