Eat Code Sleep – repeat
Two words are anagrams of one another if their letters can be rearranged to form the other word. Given a string, split it into two contiguous substrings of equal length. Determine the minimum number of characters to change to make the two substrings into anagrams of one another.
We are very near to our goal now. The enemy is being weakened continuously. But alas, sensing his fall, the hacker has spread a worm into our network. It is consuming all our files at a tremendous rate and must be stopped at all costs. The only way to stop it is to enter a specific code number in to the worm.
The first and the last digits of the price were not readable. Although, the number of nails in the box could be read clearly. The box read,

Someone is trying to break into Thapar University’s Database and steal sensitive research information. It is now up to us to stop this attack. Fortunately our defence mechanisms have traced the attacks to their source. The fastest way to stop the attacks is to disable the source.
Given two strings, A and B, output true if B is a substring of A and false otherwise. The first line contains the number of test cases T. This is followed by T lines each consisting of pairs of binary strings A and B.
For a given positive integer K of not more than 5 digits, write the value of the smallest palindrome larger than K to output. Numbers are always displayed without leading zeros. The first line contains integer T, the number of test cases. Integers K are given in the next t lines.
A simple recursive method to generate a numeric palindrome from any number is to reverse its digits and add it to the original. If the sum is not a palindrome (which means, it is not the same number from left to right and right to left), repeat this procedure.
Reversed number is a number written in Arabic numerals but the order of digits is reversed. The first digit becomes last and vice versa. For example, if the number is 1245, it will become 5421. Note that all the leading zeros are omitted. That means if the number ends with a zero, the zero is lost by reversing (e.g. 1200 gives 21).
Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja’s account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US. Calculate Pooja’s account balance after an attempted transaction.
The captain of the ship TITANIC needs to select the crew for the ship. The contestants have to stand in a line. They are given the numbers in the order in which they stand, starting from 1. The captain then removes all the contestants that are standing at an odd position.
