+# Rabin–Karp String Search Algorithm in R
+# Author: sgindeed
+# Description: Finds all occurrences of a pattern in a given text using a rolling hash technique.

+# Ask user for input
+text <- readline(prompt = "Enter the text: ")
+pattern <- readline(prompt = "Enter the pattern to search: ")
+
+# Convert both to lowercase for case-insensitive matching
+text <- tolower(text)
+pattern <- tolower(pattern)
+
+# Get lengths
+n <- nchar(text)
+m <- nchar(pattern)
+
+# Handle empty or invalid inputs
+if (m == 0) {
+  cat("Empty pattern. Nothing to search.\n")
+  quit(save = "no")
+}
+
+if (m > n) {
+  cat("Pattern is longer than text. Pattern not found in text.\n")
+  quit(save = "no")
