+Converts an integer to a suffixed string, adding `am` or `pm` based on its value.
+
+- Use the modulo operator (`%`) and conditional checks to transform an integer to a stringified 12-hour format with meridiem suffix.
+
+```js
+const getMeridiemSuffixOfInteger = num =>
+  num === 0 || num === 24
+    ? 12 + 'am'
+    : num === 12
+    ? 12 + 'pm'
+    : num < 12
+    ? (num % 12) + 'am'
+    : (num % 12) + 'pm';
+```
+
+```js
+getMeridiemSuffixOfInteger(0); // '12am'
+getMeridiemSuffixOfInteger(11); // '11am'
+getMeridiemSuffixOfInteger(13); // '1pm'
+getMeridiemSuffixOfInteger(25); // '1pm'
+```
