React code implementation

Task 1. There is a monkey which can walk around on a planar grid. The monkey can move one space at a time left, right, up or down. That is, from (x, y) the monkey can go to (x+1, y), (x-1, y), (x, y+1), and (x, y-1).Points where the sum of the digits of the absolute value of the x coordinate plus the sum of the digits of the absolute value of the y coordinate are lesser than or equal to 19 are accessible to the monkey. For example, the point (59, 79) is inaccessible because 5 + 9 + 7 + 9 = 30, which is greater than 19. Another example: the point (-5, -7) is accessible because abs(-5) + abs(-7) = 5 + 7 = 12, which is less than 19.How many points can the monkey access if it starts at (0, 0), including (0, 0) itself?Input sample:There is no input for this program.Output sample:Print the number of points the monkey can access. It should be printed as an integer — for example, if the number of points is 10, print “10”, not “10.0” or “10.00”, etTask 2. Implement aa siomple calculator that could accept only integers and perform calculation including: +, -, /,*, () and follow priority of operations.Input = (2+3) * (20-10)Result = 50
