Can anyone please help me with this solving this code in Kotlin. I tried a lot but it's not going well.

Question

You need to define a function, which takes a letter and a text as arguments, and returns the number of times the given letter appears in the given text.
Sample Input:
e
awesome
Sample Output:
2
fun main(args: Array<String>) {
val letter: Char = readLine()!![0]
val text: String = readLine()!!
val result = letter_count(letter, text)
println(result)
}

Answer 1

fun main() {
val c = readLine()!!
val txt = readLine()!!
print(txt.filter(){
it.toString().equals(c)}
.count())
}
If you want to ignore case, use: .equals(c, true)

Answer 2

//I guess this will help you
fun letterCount(letter: String, text: String): Int {
return text.toList().count{ it == letter.single() }
}

Thank you Coding Cat [Mouse searching]

Answer 4

Sorry, didn't read your post right. Have changed my solution to a funktion with return value 😉

Hi

Answer 6

Thanks Ananya. It didn't figure out correctly.
However, I was able to sort it out. Here it is:
fun main(args: Array<String>) {
val ch :Char = readLine()!![0]
val str : String = readLine()!!
var frequency = 0
for (i in 0..str.length - 1) {
if (ch == str[i]) {
++frequency
}
}
println("$frequency")
}

Ananiya Jemberu
nothing! I've tryed your solution. It works fine for me 👍
Didn't know this .single() funktion since now. Very nice 😀

Answer 8

yes, the force is with me.

Answer 9

fun main(args: Array<String>) {
val ch :Char = readLine()!![0]
val str : String = readLine()!!

for (i in 0..str.length - 1) {
if (ch == str[i]) {
++frequency
}
}
println("$frequency")
}

Answer 12

Ow, thanks :) Coding Cat [Mouse searching]
it just convert single string to char

Answer 13

fun letter_count(letter:Char, text:String) : Int {
var count: Int = 0
for (c in text) {
if (c == letter) count += 1
}
return count
}
fun main(args: Array<String>) {
val letter: Char = readLine()!![0]
val text: String = readLine()!!
val result = letter_count(letter, text)
println(result)
}

Answer 14

fun main() {
val c = readLine()!!
val txt = readLine()!!
var count = letterCount(c, txt)
println(count)
println(letterCount(c, txt))
}
fun letterCount(c: String, txt: String): Int{
return (txt.filter(){
it.toString().equals(c)}.count())
}

Answer 15

fun main() {
val c = readLine()!!
val txt = readLine()!!
var count = letterCount(c, txt)
println(count)
println(letterCount(c, txt))
}
fun letterCount(c: String, txt: String): Int{
return (txt.filter(){
it.toString().equals(c)}.count())
}

if (ch == str[i]) {
++frequency
}
}
println("$frequency")
}
