Write a java program. Zeeshan wanted to increase his typing speed competative programming contests. His friend suggested him to type the sentence "the quick brown fox jumps over the lazy dog" repeatedly. This sentence is called pangram because it contains every letter of the alphabet. After typing the sentence several times, Zeeshan became bored with it so he started to look for the pangrams. Given a sentence s as a string, determine weather it is a pangram or not. Assume that thestring would be in lowercase. Write a method named isPangramSentence(String sentence) thet accepts a string asargument and return true if the sentence is true if the sentence is pangram otherwise returns false.
Can you use Python programming language to to this question? Thanks
Could you solve this Question please? Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False. Implement has_duplicates by creating a histogram using the histogram function above. Do not use any of the implementations of has_duplicates that are given in your textbook. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates. Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following. aaa has duplicatesabc has no duplicates Print a line like one of the above for each of the strings in test_dups. Obs:Copy the code below into your program def histogram(s): d = dict() for c in s: if c not in d: d[c] =…
Write a C++ program which can check a C-string containing a password to see if it is in the hills initial password format, i.e. mmmDDYY.fl, where:mmm - three lowercase characters for month, e.g. "mar" is March (you don’t need to verify that it’s an actual month, just three lowercase characters)DD - two digits for day (you don't need to verify that it's an actual day, any two digits are ok)YY - two digits for year. - a periodfl - two lowercase characters for first and last initials You can write your program entirely in main() if you want, and make sure to test out with a few different passwords, both in the format, and not in the format.
Write a regular expression that defines strings that have an even (but nonzero) number of "a" characters followed by an odd number of "b" characters. For example, aab, aabbb, aaaab, and aaaabbb should all match the regular expression.
Write a program that creates an input function to enter a string. Then use .isalpha method to find ifthe first character in the string starts with a letter or a non-letter. (Hint: use indexing and if and if notfunction). Make sure to print the two statements ‘Your string starts with a letter’ and ‘Your stringcontains a non-letter’)
Write a function that takes in input as a string. For all characters which are numeric, double its value and, if it istwo digits, then replace it with the sum of its digits (e.g., 6 12 3 whereas 3 6). For all characters which arein uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with (e.g.,m M and N n). The program should keep asking the user to enter strings until they either enter 'q' or
Write a Python function countSpace() that takes a string as parameter, finds and returns the number of spaces in the string.Attention: Not all whitespaces will be counted, only the number of space (' ') character will be counted.Write only the answer of what is asked. Unnecessary statements may result in loss of points. I.e. write only the function. pls use pyhton and answer fastly thank u

Given string stringVal on one line, integer idxBegin on a second line, and integer desiredLen on a third line, output the substring of stringVal starting at position idxBegin and with length desiredLen. End with a newline. Ex: If the input is: Fuzzy bear 3 4 then the output is: zy b Note: Using a pre-defined string function, the solution can be just one line of code. #include <iostream>#include <string>using namespace std; int main() { string stringVal; int idxBegin; int desiredLen; getline(cin, stringVal); cin >> idxBegin; cin >> desiredLen; /* Your code goes here */ return 0;}

Given a letter, created a function which returns the nearest vowel to the letter. If two vowels are equidistant to the given letter, return the earlier vowel. Examples nearest Vowel("b") - "a" nearestVowel("s") → "u" nearest Vowel ("c") → "a" nearest Vowel("i") → "i"
