Minimum Steps to Target
You have a grid of size m x n, where each cell has a non-negative integer cost. You start from the top-left corner (0,0) and need to reach the bottom-right corner (m-1,n-1) while minimizing the total cost. Write a function to compute the minimum cost path to reach the target cell.
Input Format:
- The first line contains two integers, m and n (1 <= m, n <= 50).
- The next m lines each contain n space-separated integers representing the costs in the grid.
Output Format:
- A single integer representing the minimum cost to reach the target cell.
Example:
Input:
2 2
1 3
2 1
Output:
3
