 In some instances, you may want to convert a Roaring bitmap into a conventional (uncompressed) bitset.
 Indeed, bitsets have advantages such as higher query performances in some cases. The following code
 illustrates how you may do so:
 
 ```C
-    roaring_bitmap_t *r1 = roaring_bitmap_create();
-    for (uint32_t i = 100; i < 100000; i+= 1 + (i%5)) {
+roaring_bitmap_t *r1 = roaring_bitmap_create();
+for (uint32_t i = 100; i < 100000; i+= 1 + (i%5)) {
      roaring_bitmap_add(r1, i);
-    }
-    for (uint32_t i = 100000; i < 500000; i+= 100) {
+}
+for (uint32_t i = 100000; i < 500000; i+= 100) {
      roaring_bitmap_add(r1, i);
-    }
-    roaring_bitmap_add_range(r1, 500000, 600000);
-    bitset_t * bitset = bitset_create();
-    bool success = roaring_bitmap_to_bitset(r1, bitset);
-    assert(success); // could fail due to memory allocation.
-    assert(bitset_count(bitset) == roaring_bitmap_get_cardinality(r1));
-    // You can then query the bitset:
-    for (uint32_t i = 100; i < 100000; i+= 1 + (i%5)) {
-        assert(bitset_get(bitset,i));
-    }
-    for (uint32_t i = 100000; i < 500000; i+= 100) {
-        assert(bitset_get(bitset,i));
-    }
-    // you must free the memory:
-    bitset_free(bitset);
-    roaring_bitmap_free(r1);
+}
+roaring_bitmap_add_range(r1, 500000, 600000);
+bitset_t * bitset = bitset_create();
+bool success = roaring_bitmap_to_bitset(r1, bitset);
+assert(success); // could fail due to memory allocation.
+assert(bitset_count(bitset) == roaring_bitmap_get_cardinality(r1));
+// You can then query the bitset:
+for (uint32_t i = 100; i < 100000; i+= 1 + (i%5)) {
+    assert(bitset_get(bitset,i));
+}
+for (uint32_t i = 100000; i < 500000; i+= 100) {
+    assert(bitset_get(bitset,i));
+}
+// you must free the memory:
+bitset_free(bitset);
+roaring_bitmap_free(r1);
 ```
 
 You should be aware that a convention bitset (`bitset_t *`) may use much more
