kotlin 16進制

Given a number in octal number system format, we have to convert it into decimal number system format.

給定八進制系統(tǒng)格式的數(shù)字，我們必須將其轉(zhuǎn)換為十進制系統(tǒng)格式。

Example:

例：

Input:num = 344Output:228

在Kotlin中將八進制數(shù)轉(zhuǎn)換為十進制數(shù)的程序 (Program to convert octal number to decimal number in Kotlin)

package com.includehelp.basicimport java.util.*//Main function Entry Point of Program fun main(arg: Array<String>) {//Input Streamval sc = Scanner(System.`in`)//Input Octal Numberprintln("Enter Octal Number : ")var octalNumber: Int = sc.nextInt()var decimalNumber=0var i = 0var isCorrectOctal=true;val octalStr = octalNumber.toString();//Check Given no is valid Ocatal Number or notfor(i in octalStr.indices){if (octalStr[i] !in '0'..'7' ){isCorrectOctal=false}}if(isCorrectOctal){//Convert Octal to Decimalwhile (octalNumber > 0) {val r= octalNumber % 10decimalNumber += (r * Math.pow(8.0,i.toDouble())).toInt()octalNumber /= 10i ++}//Print Decimal Numberprintln("Decimal: $decimalNumber")}else{System.err.println("Invalid Octal Number !!")} }

Output

輸出量

Run 1: Enter Octal Number : 344 Decimal: 228 ------- Run 2: Enter Octal Number : 48 Invalid Octal Number !! ------- Run 3: Enter Octal Number : 47 Decimal: 39
