Question
JAVA
turn this psuedo code into java code.
USING NO LOOPS! ALL LOOPS MUST BE TURNED INTO RECURSIVE CALLS.
English:
1. Prompt for and read a number between 1 and 5. Repeat this step until the input is 1..5.
2. Repeat the following multiple times according to the number read in step 1.
a. Read in a list of integers ending with a 0. The 0 marks the end of the input and is not considered part of the list
b. Print the largest and smallest integers in the list.
c. If only a zero appears in the list, print an error message
Psuedo code:
begin repeat prompt user to enter a number from 1 to 5 read number until number is from 1 to 5 repeat number times decrement number read input if input 0 print error message else set min to input set max to input read input repeat while input is not 0 if input min then set min to input else if input max then set max to input end if end if read input end repeat print max print min end if end repeat endExplanation / Answer

this.printLargestandsmallest(0,100000000);//calling to read list...and to print largest and smallest
ntimes(n-1);
return ;
}
void printLargestandsmallest(int L,int M)//which reads list and prints largest and smallest
{
System.out.println("Enter number ");//reading list..
int n=sc.nextInt();//readinging number
if(n!=0)
{
if(L<n)L=n;//updating largest element
if(M>n)M=n;//updating smallest element
printLargestandsmallest(L,M);
return;
}
else
{
if(L==0)
{
//showing error message...if first zero entered
System.out.println("Error: you have not enetered any numbers");
return;
}
else
{//printing largest and smallest...
System.out.println("Largest among given :"+L);
System.out.println("Smallest among given :"+M);
return;
}
}
}
public static void main(String argv[])
{
LargerandSmaller r = new LargerandSmaller();
int n = r.readint();
r.ntimes(n);
}
}
output:-
run:
Enter number between 1 and 5:
