SDE - 2

You are given two strings A and B. Find the index of the first occurrence of A in B. If A is not present in B, then return -1.

For Example:

A = “bc”, B = “abcddbc”.
String “A” is present at index 1, and 5(0-based index), but we will return 1 as it is the first occurrence of “A” in string “B”.

Chess tournament is going to be organized in Ninjaland. There will be C chess players going to attend the tournament. All the players will be staying in a hotel. The hotel has N free rooms available for the players, where one player will choose one room to live in. The ith room is at position[i] in the hotel. All rooms are in distinct positions.

Focus level of a chess player is defined as the minimum distance between his room and the room of another player. The overall focus of a tournament is defined as the minimum focus level among all players. You as an organizer obviously want the overall focus as high as possible so you assign the rooms to players such that the overall focus is as high as possible.

For example,

let say we have 3 players and 5 rooms available and the rooms are at positions:  1 2 3 4 6
Here the optimal allocation is in rooms 1 3 6 and the overall focus level is 2.

You are given an Array/List Arr of non-negative integers. Your task is to return the number of Squareful permutations of the array.

An array is called Squareful if the sum of every pair of adjacent elements is a perfect square.

Example

ARR[1,3,6] is a Squareful array as 1+3=4 i.e. 2^2 , 3+6=9 i.e. 3^2.

Two permutations ARR1 and ARR2, are different from each other if there exit an index i such that ARR1[i] != ARR2[i].

Example:

[1,6,3] and [6,1,3] are different permutations.
