You will be given two sentances S1, S2 your task is to find a. Number of common words between S1, S2 b. Words in S1 but not in S2 c. Words in S2 but not in S1

To solve the problem of analyzing the two sentences $S1$ and $S2$, we can follow these clear steps:

1. Break Down the Problem

We need to accomplish three tasks:

1. Count the number of common words between $S1$ and $S2$.
2. Identify the words that are present in $S1$ but not in $S2$.
3. Identify the words that are present in $S2$ but not in $S1$.

2. Relevant Concepts

To tackle these tasks, we can use the concepts of set operations in mathematics. In Python or programming languages, we would typically convert the sentences into sets of words, allowing us to easily perform operations like intersection (common words) and set difference (words unique to each sentence).

3. Analysis and Detail

1. Common Words: To find the common words, we will compute the intersection of the two sets.

   $\text{Common Words} = S1 \cap S2$

2. Words in S1 but not in S2: This can be found using the set difference operation.

   $\text{Words in } S1 \text{ but not in } S2 = S1 - S2$

3. Words in S2 but not in S1: Similarly, this can be computed as:

   $\text{Words in } S2 \text{ but not in } S1 = S2 - S1$

4. Verify and Summarize

After performing these set operations based on the given sentences, we can summarize the findings based on the output of these operations.

Final Answer

Using the steps described, we can determine:

• The number of common words: $\text{len}(S1 \cap S2)$
• The words in $S1$ but not in $S2$: $S1 - S2$
• The words in $S2$ but not in $S1$: $S2 - S1$

Please provide the two sentences $S1$ and $S2$ for specific results.
