You are given a strings and an integer k. You can choose any character of the string and change it to any other uppercase English character. You can perform this operation most k times. Return the length of the longest substring containing the same letter you can get after performing the above operations. Example 1: Input: s= "ABAB", k = 2 Output: 4 Explanation: Replace the two 'A's with two 'B's or vice versa. Example 2: Input: s= "AABABBA", k = 1 Output: 4 Explanation: Replace the one 'A' in the middle with 'B' and form "AABBBBA". The substring "BBBB" has the longest repeating letters, which is 4. Constraints: 1 <= s.length <= 105 s consists of only uppercase English letters. 0 <= k <= s.length

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. Ex: If the input is 6, the output is: 011 (6 in binary is 110; the algorithm outputs the bits in reverse).
use java programming make a program that takes in a string. This string will be altered by switching the characters by asking two indices to switch. However, there is a twist. If the index to be switched is a vowel character, find the nearest non-vowel character and switch it instead. If the distance to the left is the same as the riht one, use the right one. Furthermore, finding the nearest non-vowel character is rotational, meaning, if you are at index '0' and the non vowel character and index '1' (right direction) is a vowel character, the new index would be the last index.
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x modulo 2 (remainder is either 0 or 1) Assign x with x divided by 2 Note: The above algorithm outputs the 0's and 1's in reverse order. Ex: If the input is: 6 the output is: 011 6 in binary is 110; the algorithm outputs the bits in reverse. Use something like print(x % 2, end=''). After the loop is over terminate the print line with print().
A finite sequence of symbols from a given alphabet will be called a string over the alphabet. A string that consists of a sequence a1, a2, a3, a4, … … … … , ?? of symbols will be denoted by the juxtaposition a1 a2 a3 a4 … … … … ??. Given the strings: ? = a2bab2and v = bab2, Evaluate the following operations for strings: (i) ԑu(ii) u + v(iii) u(u| v)(iv) v | (v | u)
Implement a mechanism for performing basic string compression using repeated character counts. The string aabccccaaa, for example, would become a2blc5a3. Your method should return the original string if the "compressed" string does not grow smaller than the original string. You can assume that the string only contains uppercase and lowercase letters (a-z).
A string S consisting of uppercase English letters is given. In one move we can delete seven letters from S, forming the word "BALLOON" (one 'B' one A, two 'L's, two 'O's and one 'N'), and leave a shorter word in S. If the remaining letters in the shortened S are sufficient to allow another instance of the word "BALLOON" to be removed, next move can be done. What is the maximum number of such moves that we can apply using python
Computer Science you are given a string X of length n and another string Y of length m ≤n. Say,the indexes p1, p2, p3, p4 and q1, q2, q3, q4 form two sub-sequences, i.e., 0 ≤ p1 < p2 < p3 < p4 < nand 0 ≤q1 < q2 < q3 < q4 < n; then, they are non-overlapping if p4 < q1.The task is to count the maximum number of non-overlapping sub-sequences of X that are thesame as Y . Thus, if X = GAXTYAWBGTAUGBTABGRGTAXB and Y = GTAB, then the answer is3 as shown by the red fonts. We cannot select the underlined GTAB as it overlaps with a red GTAB(i.e., among overlapping sub-sequences, you can select only one of them).Describe an O(m + n) time algorithm to obtain the count. Write a pseudo-code.
Write a program that gets a list of integers from input, and outputs negative integers in descending order (highest to lowest). Ex: If the input is: 10 -7 4 -39 -6 12 -2 the output is: -2 -6 -7 -39 For coding simplicity, follow every output value by a space. Do not end with newline.
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110
Trace this C code: What is the output of the following program segment? (Trace code and show your work) int i = 1, j = 1, k = 5; while (i+j < k) { printf("i = %d j = %d k = %d \n", i, j, k); i = j + k; j = i + k; k = i + j; } printf("i = %d j = %d k = %d \n", i, j, k);

Write a program to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. Hint: Use string[start:end] to get a substring when parsing the string and extracting the date. Use the split() method to break the input into tokens. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003 use PYTHON starting with : months = { "January": 1, "February": 2, "March": 3, "April": 4, "May": 5, "June": 6, "July": 7, "August": 8, "September": 9, "October": 10, "November": 11, "December": 12,} import refor data in ['March 1, 1990', 'April 2 1995', '7/15/20', 'December 13, 2003', -1]: if data == -1: break if re.match(r'(\w+) (\d{1,2}), (\d{4})', data) == None: continue output = data.split(" ")…
