Search & Filtering
Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with decimal part.
Write a program that inputs several(three) lines of text and a search string, and determines the total occurrences of the string in the lines of text.
question is related to number string i passed two test cases as 1. I am 25 years and 10 months old---output(sum is 30, avg is 17.5) 2. tech foundation 35567 output(sum is 35567, avg is 35567.0)---got 2 text cases
but iam not getting 3. anjali25 is python4 expert output(sum=29, avg=14.5)
a=input().split()
sum=0
count=0
for i in a:
is_digit=i.isdigit()
if is_digit:
number=i
count+=1
sum=sum+int(number)
print(sum)
avg=sum/count
print(avg)
Triplet Sum
Given an array n integers, find and print all the unique triplets (a, b, c) in the array which give the sum K. (a+b+c=K).Input
The first line of the input will be space separated integers, denoting the elements of the array. The second line of the input will be an integer denoting the required sum KOutput
The output should be multiple lines, each line containing a unique triplet. The elements of the triple must be sorted in increasing order and all the triplets printed must be sorted in increasing order. Print "No Matching Triplets Found" if there are no triplets with the given sum.Explanation
When the given array is [0, 1, 2, 3, 5, 7, 13, 17, 19, 19] and the required sum is 22, the triplets (0, 3, 19), (0, 5, 17), (1, 2, 19), (2, 3, 17) and (2, 7, 13) have the given sum 22.
Sample Input 1
0 12 17 8 9 21
29
Sample Output 1
(0, 8, 21)
(0, 12, 17)
(8, 9, 12)
Sample Input 2
0 1 2 3 5 7 13 17 19 19
22
Sample Output 2
(0, 3, 19)
(0, 5, 17)
(1, 2, 19)
(2, 3, 17)
(2, 7, 13)
Non-Adjacent Combinations of Two Words
Given a sentence as input, find all the unique combinations of two words and print the word combinations that are not adjacent in the original sentence in lexicographical order.Input
The input will be a single line containing a sentence
The output should be multiple lines, each line containing a valid unique combination of two words. The words in each line should be lexicographical order and the lines as well should be in lexicographical order. A valid combination will not contain the words that appear adjacent in the given sentence. Print "No Combinations" if there are no valid combinations

Given a matrix of order M*N and a value K, write a program to rotate each ring of the matrix clockwise by K elements. If in any ring has less than or equal to K elements, then don’t rotate that ring.
Input
The first line of input will be two space-separated integers, denoting the M and N.
The next M lines will contain N space-separated integers.
The next line will contain an integer, denoting K.
Output
If the given K is 3. Rotate each ring of the matrix by 3 elements.
In the above matrix, the elements (1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5) is a ring, similarly, the elements (6, 7, 11, 10) will make a ring.
Therefore, by rotating each ring in clockwise direction by 3 elements will give (13, 9, 5, 1, 2, 3, 4, 8, 12, 16, 15, 14) and (10, 6, 7, 11). So the output should be

Rearrange Numbers in String
Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with the decimal part.
Input
The input will be a single line containing a string.
Output
The output should be a single line containing the modified string with all the numbers in the string re-ordered in decreasing order.
Explanation
For example, if the given string is "I am 5 years and 11 months old", the numbers are 5, 11. Your code should print the sentence after re-ordering the numbers as "I am 11 years and 5 months old".
Sample Input
I am 5 years and 11 months old
Sample Output
I am 11 years and 5 months old
Sample Input
I am 17 I want 18 but 20or24 ok
Sample Output
I am 24 I want 20 but 18or17 ok
Sample Input
I have learnt 3% of Python 4 for 45 days
Sample Output
I have learnt 45% of Python 4 for 3 days
You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.
Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.
Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.
After the update, all the previous rotation operations have to be applied to the updated initial matrix.
Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.
