Given a map of the city and the network range, the task is to determine the minimum number of the tower so that every house is within range of at least one tower. Each tower must be installed on top of an existing house.
Input: range : 1 house : 1 2 3 4 5 Output: 2 Input: range : 2 house : 7 2 4 6 5 9 12 11 Output: 3
All cities can be covered by inserting 2 towers i.e. at house 2 and 4.
All cities can be covered by inserting 3 towers i.e. at house 4, 9 and 12.
- First, sort all the element.
- Count only once and then traverse till its middle house.
- After this again traverse till tower range.
- Again repeat 1, 2, 3 step till all the houses are covered.
Below is the implementation of above approach:
Time Complexity: O(nlogn)
Space Complextity: O(1)
- Minimum number of changes required to make the given array an AP
- Minimum number of operations required to reduce N to 1
- Minimum deletions required such that any number X will occur exactly X times
- Minimum number of days required to complete the work
- Minimum number of bottles required to fill K glasses
- Minimum number of swaps required to sort an array | Set 2
- Minimum number of swaps required to sort an array
- Find out the minimum number of coins required to pay total amount
