Evaluate Indexed Arithmetic Equations
ZipRecruiter● EasyNEW GRADOAProblem statement
The four arrays are aligned. At index i, apply operator +, -, *, or / to left[i] and right[i], and report whether the exact mathematical result equals expected[i].
Division by zero is false. Division is true only when the quotient is an integer equal to expected.
Function
evaluateEquations(left: int[], right: int[], expected: int[], operators: String[]) → boolean[]Examples
Example 1
left = [2,5,3,8]right = [3,2,4,2]expected = [5,3,12,4]operators = ["+","-","*","/"]return = [true,true,true,true]Each supported operation evaluates true.
Example 2
left = [1,2]right = [1,2]expected = [3,5]operators = ["+","*"]return = [false,false]Incorrect expected values return false.
Constraints
0 <= left.length <= 100000- All arrays have equal length; integer values are in
[-10000,10000].
