This C program reverses the order of words in a given string while preserving the characters within each word.

• 1. Split the string into words using space as a delimiter. Example: 'Oracle @ App Dev' -> ['Oracle', '@', 'App', 'Dev']

• 3. Join the reversed array back into a single string with spaces. Example: 'Dev App @...read more

Print all possible paths from start to end in a linear way, moving either one or two steps right.

• Use dynamic programming to solve the problem

• Create a 2D array to store the number of paths to each position

• Start from the end position and work backwards

• At each position, calculate the number of paths by summing the number of paths from the next two positions

• Print all the paths by backtracking from the start position

Generate a tree structure from CSV values with a maximum height of 3, ensuring proper hierarchy.

• Read the CSV file line by line to extract values like E1:12, E2:32.

• Create a root node 'E' and add child nodes based on the extracted values.

• For each child node (e.g., E1), create its children (e.g., E11, E12) based on the specified count.

• Ensure that if E1 is not present, its children (E11, E12) are not included.

• Example: If C...read more

The program prints the substring after a specified character has occurred a certain number of times in a given string.

• Iterate through the string to find the specified character.

• Keep track of the count of occurrences of the character.

• Once the count reaches the specified count, extract the substring after that position.

• Handle corner cases such as when the character is not in the string or when it doesn't occur the specif...read more
