Problem: Given a number N. The task is to complete the function convertFive() which replace all zeros in the number with 5 my code| plz validate any help me
public class Replaceall0swith5 {
public static void convertFive(int n) {
//add code here.
int digit, sum = 0;
while (n > 0) {
digit = n % 10;
if (digit == 0) {
digit = 5;
}
sum = sum * 10 + digit;
n = n / 10;
}
System.out.print(n + " All O's replaced with 5 " + sum);
}
public static void main(String[] args) {
Replaceall0swith5.convertFive(1004);
}
}
Try this.
public static void convertFive(int n) {
int sum = 0;
for (int rank = 1; n > 0; n = n / 10, rank *= 10) {
int digit = n % 10;
if (digit == 0)
digit = 5;
sum = sum + digit * rank;
}
System.out.print(n + " All O's replaced with 5 " + sum);
}
n | digit | rank | sum |
---|---|---|---|
1004 | 1 | 0 | |
100 | 4 | 1 | 4 |
10 | 0 -> 5 | 10 | 54 |
1 | 0 -> 5 | 100 | 554 |
0 | 1 | 1000 | 1554 |
