Hackerrank Sherlock and Anagram Solution

By Sidharth Patnaik -
This is the solution to the Sherlock and Anagram problem found in the strings section of the algorithm domain.

Screenshot



The Code
import collections
def solve(x):
    d = collections.defaultdict(int)
    lst = list(x)
    n = len(lst)
    for i in xrange(n):
        for l in xrange(1, n-i+1):
            sub = lst[i: i+l]
            sub.sort()
            d["".join(sub)] += 1
    s = 0
    for v in d.values():
        s += v*(v-1)/2
    return s

for t in xrange(input()):
    print solve(map(str,raw_input()))

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

This program will help you in creating an simple Employee Management System using java language. In this program a class emp is used which has name, id and salary as data members. inside it there are two methods namely get() and disp() which work as getting user input and displaying the output. Scanner class is used as well. This program is an implementation of array of objects. Sample Output : The Code here: import java.util.*; class emp { public String name; public int id,sal; public void get() { Scanner s=new Scanner(System.in); System.out.print("Enter The Name: "); name=s.next(); System.out.print("Enter The id: "); id=s.nextInt(); System.out.print("Enter The sal: "); sal=s.nextInt(); s.close(); } public void disp() { System.out.println("The Name of the employee is "+name+" having id: "+id+"and a salary worth to: "+sal); } } class MainClass extends emp { publ

This is an implementation of the Bit Stuffing popularly used in data communication, also known as one of the concepts of Framing data bits. To know more please  click here. Sample Output: This is a sample output with data binary data entered as 11001111110. Program Code: import java.util.*; public class BitStuffing { public static void main(String[] args) { System.out.print("Enter the Binary message: "); Scanner sn=new Scanner(System.in); String data = sn.nextLine(); String res = new String(); String out=new String(); int counter = 0; for(int i=0;i<data.length();i++) { if (data.charAt(i)!='1' && data.charAt(i)!='0') { System.out.println("Enter only Binary values!!!"); return; }
