This function initializes a mutable map to keep track of the count of each unique character in the input CharSequence. It then iterates through each character in the CharSequence, updating the count in the map. Finally, the map is returned with the count of each unique character.
Arrange the code in the correct order.
val charCountMap = mutableMapOf<Char, Int>()
return charCountMap
val count = charCountMap.getOrDefault(char, 0)
}
}
fun countChars(charSeq: CharSequence): Map<Char, Int> {
charCountMap[char] = count + 1
for (char in charSeq) {
