1. please explain

2. Ankit ,
   What part you couldn’t understand ?
   Can you debug & check & let me know any difficulty in understanding it .

   1. could you explain line by line please,, each line what exactly doing, please . i m weak in C .

      1. Ankit
         First I create a dictionary in which i save for every key , what is the next key a user can press.(adjacent keys as value)
         Now it use a dynamic approach.
         First number of moves for level 1 is calculated for every key.
         Then number of moves for level 2 is calculated for every key using level 1 data.
         Similarly number of moves for level n is calculated for every key.

3. if possible, can you please post code in PHP as well..

   1. No Karina
      I don’t work in PHP.
      But it must be simple once you understand the above logic clearly.

   2. Try spending more time on the page and understand it.

4. i could not understand

   for(int k=0 ; k < temp.Length;k++)
   {
   count+=max[i-1,temp[k] – ‘A’];
   }

   If it is possible. please could each level of result.
   for example : level 1 = 10 ,level 2 = 36 like..

5. package com;

   import java.util.Map;
   import java.util.TreeMap;

   public class IgInfotech {

   public static void main(String[] args) {
   Map myDictionar= new TreeMap();
   myDictionar.put(“A”, new char[] { ‘A’, ‘B’,’D’ });
   myDictionar.put(“B”, new char[] { ‘A’, ‘B’,’C’,’E’ } );
   myDictionar.put(“C”, new char[] { ‘F’, ‘B’,’C’ });
   myDictionar.put(“D”, new char[] { ‘A’, ‘G’,’D’,’E’ });
   myDictionar.put(“E”, new char[] { ‘F’, ‘B’,’D’,’E’,’H’ });
   myDictionar.put(“F”, new char[] { ‘I’, ‘F’,’C’,’E’ });
   myDictionar.put(“G”, new char[] { ‘D’, ‘G’,’H’ });
   myDictionar.put(“H”, new char[] { ‘G’, ‘H’,’I’, ‘E’,’J’});
   myDictionar.put(“I”, new char[] { ‘H’, ‘I’,’F’ });
   myDictionar.put(“J”, new char[] { ‘H’, ‘J’ });

   int level=3;
   int[][] max = new int[level][10];

   for(int i=0 ; i < 10 ; i++)
   {

   max[0][i]=1; //level 1 count=1 for every 10 charcharactor of the keyboard

   }

   for(int i=1 ;i < level;i++ )
   {

   int j=0;

   for (String p: myDictionar.keySet()) //run 10 times
   {

   int count=0;

   char[] temp =myDictionar.get(p);

   for(int k=0 ; k < temp.length;k++)
   {
   System.out.println("DIFF START");
   System.out.print("A:"+('A'-'A'));
   System.out.print('B'-'A');
   System.out.print('D'-'A');
   System.out.println("DIFF END");
   count=count + max[i-1][temp[k] -'A'];//'A', 'B','D'
   // System.out.println("count:"+count+" max["+i+"- 1][temp["+k+"]-A]"+max[i-1][temp[k] -'A']);

   }

   max[i][j]=count;

   j++;

   }

   }

   int sum=0;

   for(int i=0;i<10;i++)

   sum+=max[level-1][i];

   System.out.println(sum);

   }

   }

   1. it is simple dynamic programming example.

      each level there is 10 keys. so we have taken 2 dimentional arry
      in which 1st demention represent level and send dimention represent place to hold the count of each kay.

      initially, when level=1 i.e
      a[0][0]=1,a[0][1]=1…….a[0][9]=1 . for each key in level one count=1

      now go the next level i.e level=2 and
      fill [1][0]=count. which is count of adjecent charactor
      which is obtained by substuting the value from the lower level array and keep on summing.

      i.e
      max[i-1][temp[k]-‘A’]
      max[previous-level][index of key in the initial count aaray]
      ….similarly substitue and store.

      finally the max get the sum of count of all the 10 key by passing the fixed current level number.

6. Not correct, did not pass all test cases… Something wrong..
