Shape Classes with Area Method Python Solution

class Rectangle:
    def __init__(self,breadth,length):
        self.breadth=breadth
        self.length=length
    def area(self):
        return self.breadth*self.length

    pass

class Circle:
    def __init__(self,radius):
        self.radius=radius
    def area(self):
        return math.pi*(self.radius**2)
    pass

Dominant Cells Python Solution

def numCells(grid):
    # Write your code here
    res = 0
    for i in range(len(grid)):
        for k in range (len(grid[0])):
            val = grid[i][k]
            flag = 1
            for ii in range (max(0,i-1),min(len(grid),i+2)):
                for kk in range(max(0,k-1),min(len(grid[0]),k+2)):
                    if (ii,kk)!=(i,k) and val<= grid[ii][kk] :
                         flag=0
                         break 
                if flag == 0:
                     break
            else:
                res+=1
    return res
