Consider an automated Cancer Detector application(CDP).CDP performs 600 tests per day.Among 600 tests 400 tests were consider as positive but original positives are 370 and from the detected negatives 150 negatives were original negatives. Calculate the accuracy, precison, specificity, sensitivity, kappa score and error value.

George is very much interested in finding anagrams. One day, his professor gave him two strings S and C. George's task is to count the occurrences of anagrams of the string C in string S.
Write a program to help George to complete this task.
Input Format
The First line of input contains the string S.
The Next line contains the string C.
Refer to the sample input for formatting specifications.
Output Format
The Output prints the count of the occurrences of anagrams of the string C in string S.
Refer to the sample output for formatting specifications.
Constraints
1 <= |S| <= |C| <= 50

IP Addresses
A valid IP address consists of exactly four integers separated by single dots. Each integer is between 0 and 255 (inclusive) and cannot have leading zeros.
For example, "0.1.2.201" and "192.168.1.1" are valid IP addresses, but "0.011.255.245", "192.168.1.312" and "192.168@1.1" are invalid IP addresses.
Given a string s containing only digits, return all possible valid IP addresses that can be formed by inserting dots into s. You are not allowed to reorder or remove any digits in s. You may return the valid IP addresses in any order.
Example 1:
Input: s = "25525511135"
Output: ["255.255.11.135","255.255.111.35"]
Example 2:
Input: s = "0000"
Output: ["0.0.0.0"]
Example 3:
Input: s = "101023"
Output: ["1.0.10.23","1.0.102.3","10.1.0.23","10.10.2.3","101.0.2.3"]

Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M.
Symbol Value
I 1
V 5
X 10
L 50
C 100
D 500
M 1000
For example, 2 is written as II in Roman numeral, just two one's added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II.
Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used:
I can be placed before V (5) and X (10) to make 4 and 9.
X can be placed before L (50) and C (100) to make 40 and 90.
C can be placed before D (500) and M (1000) to make 400 and 900.
Given an integer, convert it to a roman numeral.
Example 1:
Input: num = 3
Output: "III"
Explanation: 3 is represented as 3 ones.
Example 2:
Input: num = 58
Output: "LVIII"
Explanation: L = 50, V = 5, III = 3.
Example 3:
Input: num = 1994
Output: "MCMXCIV"
Explanation: M = 1000, CM = 900, XC = 90 and IV = 4.

String
Replacement
Program Description
Take
a string as input. The input string consists of numbers also. Generate a new
string from the input string in such a way that the numbers in the string
should be replaced by a character which is generated by considering the
previous character in the following manner:
The
new character is generated by adding the ascii value of previous character with
the number and getting the character for the present location.
Example:
If the previous character is a and the number is 9 then take the 9th
character after a which is j and replace the number by j.

Chain of
pearls
Program Description
Saif
likes kareena and he presented her a chain of pearls. The pearls are red and
green in colors. Saif likes chains in which the red pearls and green pearls alternate
each other i.e., R followed by G or G followed by R. So he wants to replace
some of the pearls in the chain to suit his liking.
Let the red pearl be
denoted as 'R' and let the green pearl be denoted as 'G'. For example 'RGRGRGR' is a Chain of Saif’s
liking but 'RGTGRRG' is not. Help Saif to calculate the minimum number of
pearls he need to replace (ex. 'R' to 'G' or 'G' to 'R') to get a chain that he
would like.
Input Format
Input consists of a single string consisting of only the letters 'R' and 'G'.
Assume that the maximum length of the input string is 75.
Output Format
Output consists of a single interger - the minimal number of pearls that Saif
need to replace.

Explanation
Example case 1.
We can change symbol 2 from 'R' to 'G' and symbol 9 from 'G' to 'R' and receive
'RGRGRGRGRG'.

Panagram
String
Program Description
Given a string as input you need to
determine whether the string is panagram or not. If the string is panagram
print the string as “Panagram String.” Otherwise print “Not a Panagram
String.”. A string is called panagram if it contains all the alphabets in
english as the characters in it.
Note: The input string contains boh uppercase and lowercase
characters in it.

String Anagrams
Sudeep
is well known for his ability in coding in his college. A district wise coding
competition is being held in the city. The competition allows the participants
to take help from others if they are unable to solve it. Sudeep has taken his
friend vijay. The task given in competition is like this: read two strings as
an input. you need to check the number of times every character repeated in
first string is exactly same as the number of times the same characters
repeated in other string. Then you need
to print “YES” otherwise we need to print “NO”.
Now Sudeep asked vijay to do the task. Vijay is dazzled by seeing the
code. Now you need to help vijay in solving the code so that they can go
through further rounds.

Vowel Count
Raju is good at handling strings. Now
Sasi has given a task to him. Sasi gives n number of strings to Raju. Now Raju
has to find out the count of the number of vowels present in each string. Help
Raju in completing the task.
Note:
Characters will be in both upper and lowercase. So irrespective of case the
count of vowel should be taken
Input:
N: Number of strings
Each Ni lines consists of a string
Constraints:
1<=N<=10
Output:
N lines each consists of count of vowels
in each Nth string

String Equality
Sanath is a well versed student in the college. A new principal came to college and he gets to know about the knowledge of Sanath. He want’s to test Sanath and he has given a task like this: Given a sentence he needs to determine whether the string contains equal number of lowercase alphabets, upper case alphabets, digits and symbols. If so he needs to say “Equality For Everyone” otherwise he needs to say “No Equality”. Sanath wants to prove his ability to the new principal. So help Sanath.
Input:
A single line consisting of input sentence
Output:
A single line either display “Equality For Everyone” or “No Equality”
