# How do you find the length of the longest substring without repeating characters C#?

## How do you find the length of the longest substring without repeating characters C#?

we can do better by use hash table. scan the string from begin to end too, use another pointer j to scan from i + 1 to end, but each time put the string at j to hash table if hash table does not contains it. otherwise, we get longest sub string from i. after scan all is, compare and get the longest one.

## What is longest substring without repeating characters?

Explanation: “abc” is the longest substring without repeating characters among all the substrings. Explanation: “wke” is the longest substring without repeating characters among all the substrings.

**How do you find the length of a substring?**

There are two ways to find the length of the longest substring: The Simple method extracts all the substrings from a string, and then calculates the length of substrings with only distinct characters. There will be [(n * (n + 1)) / 2] substrings in a string of n characters.

### What is the time complexity for finding the longest substring?

Since we are using two for loops for both the strings ,therefore the time complexity of finding the longest common substring using dynamic programming approach is O(n * m) where n and m are the lengths of the strings.

### What is the time complexity for finding the longest substring that is common in string S1 and S2?

The time complexity for finding the longest substring that is common in string S1 and S2 is Ɵ (n1 + n2).

**What is a time complexity for finding the longest substring that is common in string s1 and S2?**

#### What is the maximum length of a string in C?

The maximum length of a string literal allowed in Microsoft C is approximately 2,048 bytes.

#### How can we find the length of a string in C?

Use the strlen() function provided by the C standard library string. h header file. char name[7] = “Flavio”; strlen(name); This function will return the length of a string as an integer value.

**How do you find the longest substring of two strings?**

Recursive Approach

- Initialise a variable res, to count the longest common substring.
- Let i and j be the index of the str1 and str2 pointing to the last character of both the strings.
- If both the characters are the same, i.e. str1[i] == str2[j], increment the value of res by 1.

## What is substring C#?

In C#, Substring() is a string method. It is used to retrieve a substring from the current instance of the string. This method can be overloaded by passing the different number of parameters to it as follows: String. Substring(Int32) Method.

## What is the length of the longest substring in a string?

For “BBBB” the longest substring is “B”, with length 1. For “GEEKSFORGEEKS”, there are two longest substrings shown in the below diagrams, with length 7

**What is the longest substring in the abdefgabef code?**

For “ABDEFGABEF”, the longest substring are “BDEFGA” and “DEFGAB”, with length 6. For “BBBB” the longest substring is “B”, with length 1.

### What is the longest possible substring with starting character as P?

Explanation: No substring exists with starting character as ‘p’ and ending as ‘p’. Find the first occurrence of C1 and last occurrence of C3. If there is any C2 in between them, then this is the longest possible substring. Otherwise, no such substring is possible.

### Which is the longest substring without repeating characters in MySQL?

“abc” is the longest substring without repeating characters among all the substrings. “wke” is the longest substring without repeating characters among all the substrings.
