How to find the smallest substring of a string?

How to find the smallest substring of a string?

Given two strings A and B, the task is to find the smallest substring of A having B as a subsequence. Smallest substring of A having B as subsequence is abcdef. Therefore, the required length is 5. Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Which is the next smallest prime palindrome greater than n?

Let’s say P = R is a the next smallest prime-palindrome greater than or equal to N . Now since R is a palindrome, the first half of the digits of R can be used to determine R up to two possibilities.

How do you mark a substring as tentative?

Move the front of the substring forwards again until you meet the histogram condition again. Move the end forwards until it fails again. If this is a shorter substring than the first, mark that as your tentative substring. Repeat until you’ve passed through the entire first string. The marked substring is your answer.

How do you find the least ending index?

The basic idea is simple: for each starting index, find the least ending index such that the substring contains all of the necessary letters. The trick is that the least ending index increases over the course of the function, so with a little data structure support, we consider each character at most twice.

Which is the smallest string containing all characters?

Explanation: “t stri” contains all the characters of pattern. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. 3- Finally, print the smallest substring containing all characters of string2.

How to calculate the length of a string?

Count all distinct characters in given string. Maintain a window of characters. Whenever the window contains all characters of given string, we shrink the window from left side to remove extra characters and then compare its length with smallest window fount so far.

How to print the minimum length of a string?

Print the minimum length window. Below is the program to implement the above algorithm: // all characters of a pattern. // length. If yes then no such # containing all characters of a pattern. # length. If yes then no such // all characters of a pattern. // length. If yes then no such
