C program to find out the maximum value of AND, OR, and XOR operations that are less than a given value
Suppose we are given two integers k and n. Our task is to perform three operations; bitwise AND, bitwise OR, and bitwise XOR between all pairs of numbers up to range n. We return the maximum value of all three operations between any two pairs of numbers that is less than the given value k.So, if the input is like n = 5, k = 5, then the output will be 4 3 4.The greatest value of AND, OR, and XOR operations between all pairs of numbers that are less than 5 are 4, 3, and 4 respectively. We can ...
Read MorePython Program to calculate function from indicator random variable from given condition
Suppose we have two values k and n. Consider a random permutation say p1, p2, ..., pn of first n natural numbers numbers 1, 2, ..., n and calculate the value F, such that F = (X2+...+Xn-1)k, where Xi is an indicator random variable, which is 1 when one of the following two conditions holds: pi-1 < pi > pi+1 or pi-1 > pi < pi+1 and Xi is 0 otherwise. We have to find the expected value of F.So, if the input is like k = 1 n = 1000, then the output will be 1996/3To solve this, we ...
Read MorePython program to print decimal octal hex and binary of first n numbers
Suppose we have a value n. We have to print Decimal, Octal, Hexadecimal and Binary equivalent of first n numbers (1 to n) in four different columns. As we know, we can express the numbers with prefix characters d, o, X and b for decimal, octal, hexadecimal and decimal respectively.So, if the input is like n = 10, then the output will be1 1 1 1 2 2 2 10 3 3 3 11 4 4 4 100 5 5 5 101 6 6 6 ...
Read MorePython program to print design door mat texture using characters
Suppose we have two numbers n and m, m will be multiple of n. We have to draw a door mat pattern with a word say "WELCOME" in the middle. The mat size will be n x m. We have to make this mat using dots(.), hyphens (-), pipe symbols (|) and the text at middle.So, if the input is like n = 5 m = 15, then the output will be------.|.------ ---.|..|..|.--- ----WELCOME---- ---.|..|..|.--- ------.|.------To solve this, we will follow these steps −for i in range 1 to n-1, increase by 2, doprint(integer of ((m-i*3)/2) number of '-', then ...
Read MorePython program to wrap a text into paragraph with width w
Suppose we have a string s and width w. We have to wrap this text into a paragraph with width w. This can be done very easily with fill() function present inside textwrap library. So we have to import textwrap library first.So, if the input is like s = "The quick brown fox jumps over the lazy dog" w = 9, then the output will beThe quickbrown foxjumpsover thelazy dogTo solve this, we will follow these steps −take the string into stake width into wcall textwrap.fill(s, w) by passing s as the first argument, and w as the second argumentExampleLet ...
Read MorePython program to show diamond pattern with 2n-1 lines
Suppose we have a number n. We have to draw a diamond pattern with asterisks with 2n-1 lines. First 1 to n lines contain 1 to n number of asterisks, and next they are decreasing from n-1 to 1.So, if the input is like n = 5, then the output will be * * * * * * * * * * * * * * * * * * * * * * * * *To solve this, we will follow these steps −for i in range ...
Read MorePython program to validate string has few selected type of characters or not
Suppose we have a string s. We have to check whether the string contains the following or not.NumbersLowercase lettersUppercase lettersNote − There may be some other symbols, but these three must be thereSo, if the input is like s = "p25KDs", then the output will be TrueTo solve this, we will follow these steps −arr := an array of size 3 and fill with Falsefor each character c in s, doif c is alphanumeric, thenarr[0] := Trueif c is in lowercase, thenarr[1] := Trueif c is in uppercase, thenarr[2] := Truereturn true when all items of arr are trueExampleLet us ...
Read MorePython program to change character of a string using given index
Suppose we have a string s, an index i and a character c. We have to replace the ith character of s using c. Now in Python, strings are immutable in nature. We cannot write a statement like s[i] = c, it will raise an error [TypeError: 'str' object does not support item assignment]So, if the input is like s = "python", i = 3, c = 'P', then the output will be "pytPon"To solve this, we will follow these steps −left := s[from index 0 to i]right := s[from index i+1 to end]return left concatenate c concatenate rightExampleLet us ...
Read MorePython program to split a string and join with comma
Suppose we have few words that are separated by spaces. We have to split these words to form a list, then join them into a string by placing comma in-between.So, if the input is like s = "Programming Python Language Easy Funny", then the output will be Programming, Python, Language, Easy, FunnyTo solve this, we will follow these steps −words := a list of words by applying split function on s with delimiter " " blank space.ret := join each items present in words and place ", " in between each pair of wordsreturn retExampleLet us see the following implementation ...
Read MorePython program to find hash from a given tuple
Suppose we have a tuple. There are few numbers are present. We have to find the hash value of this tuple by using hash() function. This is a built-in function. The hash() function can work on some datatypes like int, float, string, tuples etc, but some types like lists are not hashable. As lists are mutable in nature, we cannot hash it. This hash value is used to map other values when we use dictionary.So, if the input is like t = (2, 4, 5, 6, 7, 8), then the output will be -1970127882925375109To solve this, we will follow these ...
