The problem requires assigning aggressive cows to stalls in a way that maximizes the minimum distance between any two cows.

• Sort the array of stall positions in ascending order.

• Use binary search to find the largest minimum distance between cows.

• Check if it is possible to assign cows with this minimum distance by iterating through the sorted array.

• If it is possible, update the maximum distance and continue binary search for a larger minimum distance.

• Return the maximum distance ...read more

The task is to count the total number of '1' in the binary representation of all numbers from 1 to N.

• Convert each number from 1 to N into its binary representation

• Count the number of '1' bits in each binary representation

• Sum up the counts of '1' bits for all numbers

• Return the sum modulo 1e9+7

The task is to reverse the words in a given string, removing any leading or trailing spaces and replacing multiple spaces between words with a single space.

• Split the string into words using spaces as delimiters

• Reverse the order of the words

• Join the reversed words with a single space between them

• Remove any leading or trailing spaces

The task is to remove consecutive duplicate characters from a given string and return the new string.

• Iterate through the characters of the string

• Compare each character with the next character

• If they are the same, skip the next character

• If they are different, add the current character to the new string

• Return the new string

The question asks to find the maximum sum that can be obtained from a path starting from any cell in the first row to any cell in the last row of a given matrix.

• Iterate through each cell in the first row and calculate the maximum sum path ending at that cell

• For each cell, calculate the maximum sum path ending at that cell by considering the three possible directions

• Store the maximum sum path ending at each cell in a separate matrix

• The maximum sum path ending at any cell in th...read more

The problem is to find the shortest path between two houses in an unweighted graph.

• The graph represents the city of Ninjaland with houses connected by roads.

• The input consists of the number of test cases, number of houses and roads, starting and ending house, and the roads between houses.

• The output is a vector of nodes representing the shortest path from the starting house to the ending house.

• If there are multiple shortest paths, any one of them can be returned.

• The constraint...read more
