Consider the following Management $-$ Trainee game. There are two types of trainees: Lazy type and Industrious type. Suppose the value to the trainee from being hired is $130$ and from not getting a position is $70.$ He has options in terms of the amount of efforts: $40$ and $80$ hours $-$ and the personal cost to him depends on his type, as expressed in the table below. The trainee's payoff is the value of being hired $($or not$)$ less the personal cost of effort. For example, if a lazy type works $40$ hours and gets the position, then his payoff is $130-50=70,$ while his payoff if he doesn't get the position is $70-50=20.$ The manager's payoff is $100$ from hiring an industrious worker; $25$ from hiring a lazy worker, and $60$ from hiring no one.

The trainee gets to know his exact type $($lazy or industrious$),$ but the manager does not know the trainee's exact type. Prior to observing the trainee's effort, the manager believes that the trainee is lazy with probability $0\mathrm{.}75$ and industrious with probability $0\mathrm{.}25.($This is the manager's prior belief. The belief has the implication that unless the manager is able acquire more information about the trainee's type, she will not hire the trainee because the expected payoff from hiring him is $0\mathrm{.}7525+0\mathrm{.}2525=43\mathrm{.}75,$ which is less than the payoff of $60$ from leaving the position open.$)$

A strategy of the trainee assigns an action $-$ work $40$ hours or $80$ hours $-$ to each possible type $-$ lazy or industrious. while a strategv for the manager assigns an action $-$ hire or fire $-$ to each possible action of the

Straightforward but Inefficient

The intuitive way to solve this problem is to get a count of digit $1$ in each number. The least important digit in a decimal number can be calculated with the modulo operator $($$$).$ If the number is grater than
