• Description: Performs element-wise inverse cosine operation on each tensor in the input tensor list.
• Formula:$$x = [{x_0}, {x_1}, ... {x_{n-1}}]\\ y = [{y_0}, {y_1}, ... {y_{n-1}}]\\$$ $$y_i=cos^{-1}({x_i}) (i=0,1,...n-1)$$

Each operator has calls. First, aclnnForeachAcosGetWorkspaceSize is called to obtain the input parameters and compute the required workspace size based on the process. Then, aclnnForeachAcos is called to perform computation.
