Write Python program to find duplicate rows in a binary matrix
Given a binary matrix contains 0 and 1, our task is to find duplicate rows and print it.Python provides Counter() method which is used here.ExampleInput: 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 Output: (1, 1, 1, 1) (0, 0, 0, 0)AlgorithmStep 1: Create a binary matrix, only 0 and 1 elements are present. Step 2: Which will have rows as key and it’s frequency as value. Lists are mutable so first, we will cast each row (list) into a tuple. Step 3: Create a dictionary using the counter method. Step 4: ...
Read MorePython program to check whether a given string is Heterogram or not
Here one string is given then our task is to check weather a given string is Heterogram or not.The meaning of heterogram checking is that a word, phrase, or sentence in which no letter of the alphabet occurs more than once. A heterogram may be distinguished from a pangram which uses all of the letters of the alphabet.ExampleString is abc def ghiThis is Heterogram (no alphabet repeated)String is abc bcd dfhThis is not Heterogram. (b, c, d are repeated)AlgorithmStep 1: first we separate out list of all alphabets present in sentence. Step 2: Convert list of alphabets into set because ...

Array is given, we have to find out maximum, minimum, secondlargest, second smallest number.AlgorithmStep 1: input list element Step 2: we take a number and compare it with all other number present in the list. Step 3: get maximum, minimum, secondlargest, second smallest number.Example code# To find largest, smallest, second largest and second smallest in a List def maxmin(A): maxi = A[0] secondsmax = A[0] mini = A[0] secondmini = A[0] for item in A: if item > maxi: maxi ...
Read MorePython code to print common characters of two Strings in alphabetical order
Two user input strings are given, our task is to print all the common characters in alphabetical order.ExampleInput: string1: python string2: program Output: opExplanationThe letters that are common between the two strings are o (1 times), p (1 time)AlgorithmStep 1: first we take two input string. Step 2: next we will do to convert these two strings into counter dictionary. Step 3: Now find common elements between two strings using intersection ( ) property. Step 4: Resultant will also be a counter dictionary having common elements as keys and their common frequencies as value. Step 5: Use elements () method ...
Read MorePython program to move spaces to front of string in single traversal
Given a string that has set of words and spaces, our task is to move all spaces to front of string, by traversing the string only once. We will solve this problem quickly in Python using List Comprehension.ExampleInput: string = "python program" Output: string= “ pythonprogram"AlgorithmStep1: input a string with word and space. Step2: Traverse the input string and using list comprehension create a string without any space. Step 3: Then calculate a number of spaces. Step 4: Next create a final string with spaces. Step 5: Then concatenate string having no spaces. Step 6: Display string.Example Code# Function to ...
