How do you find the shortest substring?

How do you find the shortest substring?

Method 1 ( Brute force solution )

1. Generate all substrings of string1 (“this is a test string”)
2. For each substring, check whether the substring contains all characters of string2 (“tist”)
3. Finally, print the smallest substring containing all characters of string2.

How do you find the shortest and longest string in a list Python?

“find shortest string in list python” Code Answer’s

1. a = [[1,0,1,2,1,1,1,3111111], [31,1,4,51,1,1,1], [1,1,6,7,8]]
2. print min(a, key=len)
3. print len(min(a, key=len))
4. print min(map(len, a))

How do you find the length of a substring?

Java String length() method example

1. public class LengthExample{
2. public static void main(String args[]){
3. String s1=”javatpoint”;
4. String s2=”python”;
5. System.out.println(“string length is: “+s1.length());//10 is the length of javatpoint string.

How do I find the smallest string in a list Python?

The Python min() function returns the lowest value in a list of items. min() can be used to find the smallest number in a list or first string that would appear in the list if the list were ordered alphabetically.

How do you find longest substring without repeating characters in a string?

For example, the longest substrings without repeating characters for “ABDEFGABEF” are “BDEFGA” and “DEFGAB”, with length 6. For “BBBB” the longest substring is “B”, with length 1. The desired time complexity is O(n) where n is the length of the string.

Is there a way to find the shortest superstring?

Find the Shortest Superstring – LeetCode. 943. Find the Shortest Superstring. Hard. Add to List. Given an array of strings words, return the smallest string that contains each string in words as a substring. If there are multiple valid strings of the smallest length, return any of them.

Which is the shortest substring that contains all characters?

A pre-candidate solution is a substring that contains all characters in the set. For example, consider the pre-candidate solutions for string 697581539 and set {1,5,9}. For a given prefix of the input string, a candidate solution is the suffix that is a pre-candidate and shortest. There may not be a candidate solution for a given prefix.

When is there no shortest substring return the empty string?

When there is no shortest substring, return the empty string. Input. The input consists of one or more cases. Each case consists of two strings, each one on a separate line.

How to find the smallest string in words?

If there are multiple valid strings of the smallest length, return any of them. You may assume that no string in words is a substring of another string in words. Input: words = [“alex”,”loves”,”leetcode\\ Output: “alexlovesleetcode” Explanation: All permutations of “alex”,”loves”,”leetcode” would also be accepted.
