SUBARRAY DIVISION
Determine how many ways Lily can divide the chocolate.
EXPLANATION CODE:
The birthday function takes a vector of integer s, and two integers d and m. The function calculates the number of ways the chocolate bar can be divided such that each segment has a sum equal to the target d.
The function initializes a variable y to 0, which will keep track of the count of valid segment distributions.
It then starts a loop that iterates through the elements of the s vector. This loop will consider all possible starting positions for dividing the chocolate bar.
Inside the loop, a variable x is initialized to 0. This variable will store the sum of each segment.
A nested loop is then used to calculate the sum of each segment. It iterates m times and adds the corresponding element from the s vector to x.
After calculating the sum of each segment, the code checks if x is equal to the target sum d. If it is, it means a valid segment distribution has been found, and the variable y is incremented by 1.
The loops continue iterating through all possible starting positions of the chocolate bar segments, checking each segment's sum against the target value.
Finally, the function returns the value of y, which represents the total number of valid segment distributions found.
