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.

• The probability of picking a red marble from the first jar is 49/50, while from the second jar it is 1/50.

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 generating five random numbers such that the first is greater...read more

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 integer value.

A cube can be divided into 27 smaller cubes with 6 cuts.

• Each cut creates one additional layer of cubes

• Three cuts are needed to divide the cube into 8 smaller cubes

• Each of the 8 smaller cubes can be divided into 3 smaller cubes with one cut

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
