To evaluate the postfix expression 4 3 1 / 2 *, we need to use a stack data structure. We start by pushing the operands (4, 3, and 1) onto the stack, and then when we encounter the operator /, we pop the two operands (3 and 1) and perform the operation (3 / 1 = 3), and then push the result (3) back onto the stack.
Next, we push the operand 2 onto the stack, and when we encounter the operator *, we pop the two operands (3 and 2) and perform the operation (3 * 2 = 6), and then push the result (6) back onto the stack.
In total, the push operation is called 5 times during the evaluation of this postfix expression. This is because we push each of the three operands (4, 3, and 1) onto the stack once, and then we push the two results (3 and 6) back onto the stack after performing the two operations.
It's important to note that the number of push operations required to evaluate a postfix expression depends on the specific expression and the operations involved. Some expressions may require more or fewer push operations, depending on the operands and operators used.
However, the basic algorithm for evaluating a postfix expression always involves pushing operands onto the stack and popping them off to perform operations, so the number of push operations will always be at least equal to the number of operands in the expression.

This pattern of trust, kindness, diligence, and increasing trust illustrates what is meant by: reaction formation. displacement. the spotlight effect. external locus of control. reciprocal determinism.
The pattern described in the question illustrates reciprocal determinism. Reciprocal determinism is the idea that our behavior, environment, and personal factors all interact with one another in a continuous cycle. In this case, Mr. Maloney's trust in his employees leads him to treat them kindly. This kindness, in turn, motivates the employees to work harder and more diligently on behalf of their employer.
The employees' increased effort and productivity then reinforce Mr. Maloney's trust in them, further strengthening the cycle of reciprocal determinism.It's worth noting that kindness and trust often go hand in hand. When we trust someone, we are more likely to treat them kindly and with respect.
Likewise, when we are treated kindly by others, we tend to trust them more. This is why Mr. Maloney's trust in his employees leads him to treat them kindly, and why their reciprocal behavior reinforces his trust in them.Trust is a crucial element in many workplace relationships, and it can be difficult to establish. However, as this example illustrates, once trust is established, it can lead to a positive cycle of reciprocal behavior that benefits both the employer and the employees.
By treating his employees with kindness and respect, Mr. Maloney has created a positive workplace culture that encourages diligence and hard work, leading to greater success for all involved.
