Question

**C Programming Language (Code With C Programming Language)**

**Problem Title : Visible Trees**

There is a legend about a magical park with N × N trees. **The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east)**. The height (in metres) of each tree is an integer between 1 and N × N, inclusive. **Magically, the height of all trees is unique**.

**Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column**. Similarly, **Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row**. **A tree X is visible if all other trees in front of the tree X are shorter than the tree X**.

**For example, let N = 3 and the height (in metres) of the trees are as follows**

6 1 8

7 5 3

2 9 4

**On the first column**, Bunga can see two trees, as the tree on the third row is obstructed by the other trees.**On the second column**, Bunga can see all three trees.**On the third column**, Bunga can see only the tree on the first row, as the other trees are obstructed by the tree on the first row.**On the first row**, Lestari can see two trees, as the tree on the second column is obstructed by the tree on the first column.**On the second row**, Lestari can see only the tree on the first column, as the other trees are obstructed by the tree on the first column.**On the third row**, Lestari can see two trees, as the tree on the third column is obstructed by the tree on the second column.

**Your task is to determine the numbers reported by Bunga and Lestari.**

**Format Input**

Input begins with a line containing an integer: N (1 ≤ N ≤ 10) representing the number of trees on each row and column. The next N lines each contains N integers representing the height (in metres) of the trees. The j^{th} integer on the i^{th} line is the height of the tree on the i^{th} row and j^{th} column between 1 to N × N, inclusive. **It is guaranteed that all trees have different heights**.

**Format Output**

**Output begins with a line containing N integers representing the number of trees visible by Bunga**. The jth integer is the number of visible trees on the jth column. **The next N lines each contains an integer representing the number of trees visible by Lestari**. The integer on the ith line is the number of visible trees on the ith row.

**Constraints**

- 1 ≤
*N*≤ 10 - j
^{th}integer on the i^{th}line is the height of the tree on the i^{th}row and j^{th}column between 1 to N × N, inclusive **It is guaranteed that all trees have different heights**
