Create 1+2=3 Android Game

By Sidharth Patnaik -
This post will guide you to create a highly interactive 1+2=3 Game. This game is based on a simple logic. Basically you have 3 number 1,2,3 which will be shuffled each time with a randomly generated operator (+,-,*,/) placed in between.

Screenshots:



Lets go through important section of the project.

Code for fetching Highscore :
public int chec()
    {
     SQLiteDatabase SQLiteDb = mh.getWritableDatabase();
     String [] col1 = {"_id","score"};
     int ch=0;
     Cursor cu1 = SQLiteDb.query("scr", col1, null, null, null, null, null);
  while(cu1.moveToNext())
  {
    ch=Integer.parseInt(cu1.getString(1));
  }
  return ch;
    }

Code For Generating Expression :
void calc()
 {
  String st="123",op="+-*/",z="",y="";
  p=0;
  Random rand=new Random();
  for(int i=0;i<3;i++)
    z=z+st.charAt(rand.nextInt((2 - 0) + 1));
  for(int i=0;i<2;i++)
    y=y+op.charAt(rand.nextInt((3 - 0) + 1));
  switch(y.charAt(0))
  {
   case '+':
    p=Integer.parseInt(z.charAt(0)+"")+Integer.parseInt(z.charAt(1)+"");
    break;
   case '-':
    p=Integer.parseInt(z.charAt(0)+"")-Integer.parseInt(z.charAt(1)+"");
    break;
   case '*':
    p=Integer.parseInt(z.charAt(0)+"")*Integer.parseInt(z.charAt(1)+"");
    break;
   case '/':
    p=Integer.parseInt(z.charAt(0)+"")/Integer.parseInt(z.charAt(1)+"");
    break;
  }
  switch(y.charAt(1))
  {
   case '+':
    p=p+Integer.parseInt(z.charAt(2)+"");
    break;
   case '-':
    p=p-Integer.parseInt(z.charAt(2)+"");
    break;
   case '*':
    p=p*Integer.parseInt(z.charAt(2)+"");
    break;
   case '/':
    p=p/Integer.parseInt(z.charAt(2)+"");
    break;
  }
  mixz(p);
  t3.setText(score+"");
  t2.setText(z.charAt(0)+""+y.charAt(0)+""+z.charAt(1)+""+y.charAt(1)+""+z.charAt(2)+"");
 }

Code for generating dummy answers and placing it
void mixz(int p)
 {
  List<Integer> dataList = new ArrayList<Integer>();
     dataList.add(p+1);
     dataList.add(p);
     dataList.add(p-1);
     Collections.shuffle(dataList);
     int[] num = new int[dataList.size()];
     for (int i = 0; i < dataList.size(); i++) 
     {
       num[i] = dataList.get(i);
     }

     b1.setText(num[0]+"");
  b2.setText(num[1]+"");
  b3.setText(num[2]+"");
 }

Code for countdown timer and operations associated with it
countDownTimer = new CountDownTimer(50000, 1000) {
    
       public void onTick(long millisUntilFinished) {
           t1.setText((millisUntilFinished / 1000)+" Secs");
           bar.setProgress((int) Math.round(millisUntilFinished / 1000.0)*2);
       }
   
       public void onFinish() {
          t1.setText("done!");
          bar.setProgress(0);
          t2.setText("Game Over, Score: "+score);
          b1.setEnabled(false);
          b2.setEnabled(false);
          b3.setEnabled(false);
          SQLiteDatabase SQLiteDb = mh.getWritableDatabase();
    ContentValues cntval=new ContentValues();
    cntval.put("score",score);
    if(chec()<score)
    {
     int num= SQLiteDb.update("scr", cntval, "chk = ?", new String []{"yes"});
    }
    ob.show();
    ot.setText(score+"");
    //Toast.makeText(getApplicationContext(), "Preferences Saved", Toast.LENGTH_LONG).show();
       }
    }.start();

Non Restoring Division Algorithm Implementation in C

This  is a Dynamic program for the implementation of the NON RESTORING Division Algorithm in C Language. Non Restoring Division uses Left Shift Operations, Twos' Compliment and Binary Addition. Screenshots[Demo] The Code #include<stdio.h> #include<malloc.h> int *a,*q,*m,*mc,*c,n,d; int powr(int x,int y) { int s=1,i; for(i=0;i<y;i++) s=s*x; return s; } void print(int arr[],int n) { int i; for(i=0;i<n;i++) printf("%d ",arr[i]); } void bin(int n, int arr[]){ int r, i = 0; do{ r = n % 2; n /= 2; arr[i] = r; i++; }while(n > 0); } void set(int array[], int x){ int i,tmp[20]={0}; for(i = x -1; i >=0; i--) tmp[x-1-i]=array[i]; for(i=0;i<x;i++) array[i]=tmp[i]; } int len(int x) { int i=0; while(powr(2,i)<=x) i++; return ++i; } void addBinary(int a1[], int a2[]) { int bi[2]={0},ca[20]={0}; int t=len(n),tmp=0; int *su=(int*)malloc(sizeof(int)*len(n)); while(t...

Hackerrank String Reduction Solution

By Sidharth Patnaik -

This is the solution to the program, solved in python. The Question can be found in the Algorithm domain of Hackerrank. Problem Statement: Given a string consisting of letters, a, b and c, we can perform the following operation: Take any two adjacent distinct characters and replace them with the third character. For example, if 'a' and 'c' are adjacent, they can replaced by 'b'. Find the smallest string which we can obtain by applying this operation repeatedly? Screenshots[Demo] The Code: def cnt(x): m={} m['a']=0;m['b']=0;m['c']=0 for c in x: if c not in m: m[c]=1 else: m[c]+=1 return m def red(x): xm=cnt(x) print x,xm if((xm['a']==0 and xm['b']==0 ) or (xm['a']==0 and xm['c']==0 ) or (xm['b']==0 and xm['c']==0)): return len(x); if((xm['a']%2==0 and xm['b']%2==0 and xm['c']%2==0) or (...
