kotlin中判斷字符串

Given a string and a character, we have to find the frequency of the character in the string.

給定一個字符串和一個字符，我們必須找到字符串中字符的頻率。

Example:

例：

Input:string = "IncludeHelp"character to find = 'e'Output:2

在Kotlin中查找字符串中字符頻率的程序 (Program to find the frequency of character in a string in Kotlin)

package com.includehelp.basicimport java.util.*//Main Function, entry Point of Program fun main(args: Array<String>) {// InputStream to get Inputval scanner = Scanner(System.`in`)//Input Stringprint("Enter String : ")val str = scanner.nextLine()//Input Character to check Frequency in Above input Stringprint("Enter Character : ")val c = scanner.next()[0]var frequency=0//Count Frequencyfor (i in str.indices){if(c == str[i]){frequency++}}//Print Frequency of Characterprintln("Frequency of $c is : $frequency") }

Output

輸出量

RUN 1: Enter String : include help team Enter Character : e Frequency of e is : 3 --- Run 2: Enter String : Kotlin is the Modern Programming Languagae Enter Character : n Frequency of n is : 4
