Given the co-effecients of X,Y and Z in a system of simultaneous equations. Find the values of X,Y and Z.
a1X + b1Y + c1Z = d1
a2X + b2Y + c2Z = d2
a3X + b3Y + c3Z = d3
Example 1:
Input:
Arr = {{5, 4, 2, 0},
{1, 4, 2, 0},
{4, 2, 9, 0}}
Output: {0, 0, 0}
Explanation: After calculating with these
given coefficient the value of X, Y, Z is
0, 0, 0.
Example 2:
Input:
Arr = {{4.2, 6, 7, 10},
{1, 2, 3, 12},
{3, 2, 2, 20}}
Output: {3, 4, -1}
Explanation: After calculating with these
given coefficient the value of X, Y, Z is
3, 4, -1.
Your Task:
You dont need to read input or print anything. Complete the function myCalculator() which takes Arr as input parameter and returns 0 in case the system is inconsistent and 1 in case the system is consistent and has infinitely many solutions. In case the system is consistent and has a unique solution, return 3 space separated integers denoting the floor values of X, Y and Z respectively.
Expected Time Complexity: O(1)
Expected Auxiliary Space: O(1)
Constraints:
-100 <= Arr[i][j] <=100
