سلام عليكم كييف الحال؟؟

بليز ابغى حل هالاسايمنت ... ماعرفت الحل

مش ضروري الحل كامل .... بس بروبلم واااحد ... اللي تعرفوونه

واكوون شاااكره لكم .. وجزاه الله خير اللي يساعدني




Problem A: Counting
Complete the function TotalChars. TotalChars returns the total number of occurrences of the character ch in each string in list. You should use the string member function to find the number of characters in a string and s[k] for the value of the kth character (indexing starts at 0).

e.g. information technology : i=2, n=3, f=1, o=4, r=1, m=1, a=1, t=1, e=1,
c=1, h= 1, l= 1, g=1, y=1
You should write this function either recursively or iteratively (non-recursively).

Problem B: Replicate
Write the function Replicate. Replicate adds new nodes to list so that nodes are replicated the number of times specified by parameter count. For example, if list is represented by:
("apple","cat","xray")
Then the call Replicate(list,3) should change list as shown below.
("apple","apple","apple","cat","cat","cat","xray", "xray","xray")

Problem C: Reverse
Complete the function Reverse. Reverse reverses the nodes of its parameter list. In writing Reverse you should maintain as an invariant. This invariant would be initialized by the statement: rev = NULL, where rev, since initially no nodes have been reversed and all nodes need to be reversed. Your code will run in O(n) time for an n-node list if you do this correctly.


Problem D: Split
Write a function ListSplit that will split a circular list containing an even number of nodes, say 2k, into two circular lists each of which contains k nodes. The function should have three parameters and should work so that the function call
ListSplit(list,sub1,sub2);
will create new lists linked to by parameters sub1, and sub2 from the list initially referenced by parameter list. After ListSplit has executed, the first parameter should be 0/NULL, i.e., new nodes are not created, but are redistributed evenly between the second and third parameters. It doesn't matter how you divide the nodes between the two lists. Note that you should make no assumptions about the values of first and second in the body of ListSplit.

اليك أختى حل السؤال الأول وهو يعد عدد تكرار كل حرف من أحرف الجملة دون حساب المسافة الخالية space

import java.util.*;
import java.io.*;
public class example{
static Scanner console= new Scanner(System.in);
public static void main(String[] args)
{
System.out.print("Please Enter aString ");
System.out.println();
String str =console.next();


char[]third =str.toCharArray();
for(int counter =0;counter<third.length;counter++)
{ char letter= third[counter];

int flage=0;
for ( int i=0; i<third.length; i++)
{
if (letter==third[i])

flage++;


}
if(counter==0)
{
System.out.println("The letter ="+letter+" is repeated "+flage+" No of Times ");
continue;
}
boolean flag=false;
for(int j=counter-1;j>=0;j--)
{
if(letter==third[j])
flag=true;
}
if(!flag)
{

System.out.println("The letter ="+letter+" is repeated "+flage+" No of Times ");
}

}
}


}

اما هذا فهو يعد عدد تكرار كل حرف من أحرف الجملة مع حساب

Space المسافة الخالية

import java.util.*;
import java.io.*;
public class triangle{
//static Scanner console= new Scanner(System.in);
public static void main(String[] args) throws IOException
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.print("Please Enter aString ");
System.out.println();
String str=br.readLine();
System.out.println(str);


char[]third =str.toCharArray();
for(int counter =0;counter<third.length;counter++)
{ char letter= third[counter];

int flage=0;
for ( int i=0; i<third.length; i++)
{
if (letter==third[i])

flage++;


}
if(counter==0)
{
System.out.println("The letter ="+letter+" is repeated "+flage+" No of Times ");
continue;
}
boolean flag=false;
for(int j=counter-1;j>=0;j--)
{
if(letter==third[j])
flag=true;
}
if(!flag)
{

System.out.println("The letter ="+letter+" is repeated "+flage+" No of Times ");
}

}
}


}
