SDE - 1

Given a string input of length n, find the length of the longest substring without repeating characters i.e return a substring that does not have any repeating characters.

Substring is the continuous sub-part of the string formed by removing zero or more characters from both ends.

You are given an array ‘ARR’ of size ‘N’ containing each number between 1 and ‘N’ - 1 at least once. There is a single integer value that is present in the array twice. Your task is to find the duplicate integer value present in the array.

For example:

Consider ARR = [1, 2, 3, 4, 4], the duplicate integer value present in the array is 4. Hence, the answer is 4 in this case.

Note :

A duplicate number is always present in the given array.

1. from which point on earth is it that if u move 1 mile south, i mile east, 1 milenorth will u reach the same point (ans = North pole)
2. using 6 matchsticks of same length create 4 equilateral triangles (ans =tetrahedron, but i was given a hint that it was in 3d)

You have been given an input integer 'N'. Your task is to print the following binary pattern for it.

Example

Pattern for 'N' = 4

1111
000
11
0

The first line contains 'N' 1s. The next line contains 'N' - 1 0s. Then the next line contains 'N' - 2 1s and so on.
