+# POLICEMEN CATCH THIEVES
+
+Given an array of size n that has the following specifications: 
+
+1-Each element in the array contains either a policeman or a thief.  
+
+2-Each policeman can catch only one thief.  
+
+3-A policeman cannot catch a thief who is more than K units away from the policeman. 
+
+We need to find the maximum number of thieves that can be caught.
+Examples: 
+## Running Tests
+
+### Input
+
+```bash
+  arr[] = {'P', 'T', 'T', 'P', 'T'},
+            k = 1.
+```
+### Output
+
+```bash 
+2
+```
+
+### Input
+```bash 
+arr[] = {'T', 'T', 'P', 'P', 'T', 'P'}, 
+            k = 2
+```
+
+### Output 
+```bash
+3
+```
