+# 19-matching-MN-to-N
+
+## 电信业务场景
+
+套餐适用M:N→N条。多个合同关联多个套餐的组合匹配，输出按套餐件数(N件)的适用明细。
+
+**M:N matching — output N records (one per detail match).**
+
+Tests the scenario where both input files may contain duplicate keys.
+The program performs a grouped match: for each key where at least one
+master record exists, the program outputs every detail record for that
+key, then skips all master records for that key.
+
+## Test data
+
+| File        | Records | Keys                          |
+|-------------|---------|-------------------------------|
+| master.dat  | 4       | KEY00001 (x2), KEY00002 (x2) |
+| detail.dat  | 5       | KEY00001 (x2), KEY00003 (x3) |
+
+- **Matched key:** KEY00001 -> 2 output records (2 detail records)
+- **Unmatched master key:** KEY00002 (skipped)
+- **Unmatched detail key:** KEY00003 (skipped)
+
+## Algorithm
+
+1. Read both files synchronously (both assumed sorted by key).
+2. When keys match: output all detail records in the group, then skip all
+   master records in the group.
+3. When master key < detail key: skip all master records with that key
+   (no matching detail).
+4. When detail key < master key: skip all detail records with that key
+   (no matching master).
+
+## Expected output
+
+- **output.dat:** 2 records x 45 bytes = 90 bytes
+- Program displays: `19-matching-MN-to-N: PASS`
+- Script displays: `19-matching-MN-to-N: ALL TESTS PASSED`
