Use binary search to efficiently find the square root of a number by narrowing down the range of possible values.

• 1. Initialize low as 0 and high as the number (n).

• 2. Calculate mid as (low + high) / 2.

• 3. If mid * mid equals n, return mid as the square root.

• 4. If mid * mid is less than n, set low to mid + 1.

• 5. If mid * mid is greater than n, set high to mid - 1.

• 6. Repeat until low exceeds high, returning the closest inte...read more

To check if a linked list is looped onto itself, we can use hashmaps.

• Create an empty hashmap

• Traverse the linked list, for each node check if it already exists in the hashmap

• If a node already exists, it means the linked list is looped

• If the traversal completes without finding a loop, the linked list is not looped

p^2-1 is divisible by 8 and 24 for all primes.

• To prove p^2-1 is divisible by 8, consider the possible remainders of p when divided by 8.

• To prove p^2-1 is divisible by 24, consider the possible remainders of p when divided by 24.

• For all primes, p^2-1 will always be divisible by 8 and 24.

Probability of rolling three unbiased dices such that a>b>c and extrapolating to five random number generators.

• The probability of rolling three unbiased dices such that a>b>c is 1/216.

• To extrapolate to five random number generators, we need to calculate the probability of generating five random numbers such that the first is greater than the second, the second is greater than the third, and so on.

• The probability of gen...read more

To maximize the probability of picking a red marble, divide the marbles unevenly, with more red marbles in one jar.

• Place 49 red marbles and 1 blue marble in one jar, and the remaining 1 red marble and 49 blue marbles in the other jar.

• This way, the blind man has a higher chance of picking the jar with 49 red marbles and 1 blue marble.

A hash map is a data structure that uses a hash function to map keys to values.

• Hash map stores key-value pairs

• It uses a hash function to compute an index for each key

StringBuffer and StringBuilder are both used to manipulate strings, but StringBuffer is thread-safe while StringBuilder is not.

• StringBuffer is synchronized, making it safe for use in multi-threaded environments.

• StringBuilder is not synchronized, making it faster but not thread-safe.

• StringBuffer is preferred when multiple threads are involved, while StringBuilder is preferred for single-threaded scenarios.

• Both classes p...read more
