$/*$

Shelia's Seashell Store has a new website. Shelia wants to display if the store is open when someone views the website.

The following problems have you implement the logic to indicate if the store is open.

You're given an integer that represents the current hour in each problem.

The store is open if the current hour is equal to or greater than the open time and less than the closing time.

Hours are represented in $24-$hour format:

$1$am $=1$

$2$am $=2$

$...$

$12$pm $=12$

$1$pm $=13$

$2$pm $=14$

$...$

$11$pm $=23$

$12$am $=0$

$*/$

$/*$

Shelia's Seashell Store is open between $8$ am $($hour $8)$ and $5$ pm $($hour $17).$

Implement the logic to determine if the store is open based on the current hour.

Examples:

isStoreOpen$(8)$ true

isStoreOpen$(12)$ true

isStoreOpen$(17)$ false

isStoreOpen$(22)$ falsepublic boolean isStoreOpen$($int currentHour$)\{$

return false;

$\}$

Shelia forgot to take into account the day of the week.

Her store is open between $8$ am $($hour $8)$ and $5$ pm $($hour $17)$ on Monday $($day M$),$ Wednesday $($day W$),$ and Friday $($day F$).$

Implement the logic to determine if the store is open based on the current hour and the current day.

NOTE: This problem uses a char to represent the current day of the week. You can use the following key:

Sunday $=\text{'}$U$\text{'}$

Monday $=\text{'}$M$\text{'}$

Tuesday $=\text{'}$T$\text{'}$

Wednesday $=\text{'}$W$\text{'}$

Thursday $=\text{'}$H$\text{'}$

Friday $=\text{'}$F$\text{'}$

Saturday $=\text{'}$S$\text{'}$

The char for the current day is always uppercase. If an invalid char is used, return false.

Examples:

isStoreOpen$(8,\text{'}$M$\text{'})$ true

isStoreOpen$(12,\text{'}$W$\text{'})$ true

isStoreOpen$(12,\text{'}$S$\text{'})$ false

public boolean isStoreOpen$($int currentHour, char currentDay$)\{$

return false;

$\}$

$/*$

Shelia's Seashell Store is open between $8$ am $($hour $8)$ and $5$ pm $($hour $17)$ on Monday $($day M$),$ Wednesday $($day W$),$ and Friday $($day F$).$

In the summer, the store is open for additional hours. On Wednesday $($day W$)$ the store stays open until $8$ pm $($hour $20)$ and is also

open Saturday $($day S$)$ from $9$ am $($hour $9)$ to $3$ pm $($hour $15).$

Implement the logic to determine if the store is open based on the current hour, the current day, and if it's summer.

Examples:

isStoreOpen$(8,\text{'}$M$\text{'},$ true$)$ true

isStoreOpen$(12,\text{'}$W$\text{'},$ false$)$ true

isStoreOpen$(12,\text{'}$S$\text{'},$ false$)$ false

isStoreOpen$(9,\text{'}$S$\text{'},$ true$)$ true

public boolean isStoreOpen$($int currentHour, char currentDay, boolean isSummer$)\{$

return false;

$\}$
