The containsMatchIn() function is used to check whether there exists any match of our pattern in the input and returns a boolean value.

Syntax:

fun containsMatchIn(input: CharSequence): Boolean

Kotlin program to demonstrate the example of containsMatchIn() function

// Example of containsMatchIn() function
fun main()
{
	// Regex to match any string starting with 'i'
	val pattern = Regex("^i")
    
	println(pattern.containsMatchIn("includehelp"))
	println(pattern.containsMatchIn("Incognito"))
