# --description--
|
||||
|
||||
You are given a collection of ABC blocks (e.g., childhood alphabet blocks). There are 20 blocks with two letters on each block. A complete alphabet is guaranteed amongst all sides of the blocks. The sample collection of blocks:
|
||||
|
||||
<pre>(B O)
|
||||
(X K)
|
||||
(D Q)
|
||||
(C P)
|
||||
(N A)
|
||||
(G T)
|
||||
(R E)
|
||||
(T G)
|
||||
(Q D)
|
||||
(F S)
|
||||
(J W)
|
||||
(H U)
|
||||
(V I)
|
||||
(A N)
|
||||
(O B)
|
||||
(E R)
|
||||
(F S)
|
||||
(L Y)
|
||||
(P C)
|
||||
(Z M)
|
||||
</pre>

# --instructions--
|
||||
|
||||
Implement a function that takes a string (word) and determines whether the word can be spelled with the given collection of blocks.
|
||||
|
||||
Some rules to keep in mind:
|
||||
|
||||
<ul>
|
||||
<li>Once a letter on a block is used, that block cannot be used again.</li>
|
||||
<li>The function should be case-insensitive.</li>
|
||||
</ul>
|
||||
|
||||
# --hints--
|
||||
|
||||
`canMakeWord` should be a function.
|
||||
|
||||
```js
|
||||
assert(typeof canMakeWord === 'function');
|
||||
```
|
||||
|
||||
`canMakeWord` should return a boolean.
|
||||
|
||||
```js
|
||||
assert(typeof canMakeWord('hi') === 'boolean');
|
||||
```
|
||||
|
||||
`canMakeWord("bark")` should return true.
|
||||
|
||||
```js
|
||||
assert(canMakeWord(words[0]));
|
||||
```
|
||||
|
||||
`canMakeWord("BooK")` should return false.
|
||||
|
||||
```js
|
||||
assert(!canMakeWord(words[1]));
|
||||
```
|
||||
|
||||
`canMakeWord("TReAT")` should return true.
|
||||
|
||||
```js
|
||||
assert(canMakeWord(words[2]));
|
||||
```
|
||||
|
||||
`canMakeWord("COMMON")` should return false.
|
||||
|
||||
```js
|
||||
assert(!canMakeWord(words[3]));
|
||||
```
|
||||
|
||||
`canMakeWord("squAD")` should return true.
|
||||
|
||||
```js
|
||||
assert(canMakeWord(words[4]));
|
||||
```
|
||||
|
||||
`canMakeWord("conFUSE")` should return true.
|
||||
|
||||
```js
|
||||
assert(canMakeWord(words[5]));
|
||||
```
|
||||

||||
# --seed--
|
||||
|
||||
## --after-user-code--
|
||||
|
||||
```js
|
||||
const words = ['bark', 'BooK', 'TReAT', 'COMMON', 'squAD', 'conFUSE'];
|

|

|

# --solutions--
|
||||
|
||||
```js
|
||||
function canMakeWord(word) {
|
||||
const characters = 'BO XK DQ CP NA GT RE TG QD FS JW HU VI AN OB ER FS LY PC ZM';
|
||||
const blocks = characters.split(' ').map(pair => pair.split(''));
|
||||
|
||||
const letters = [...word.toUpperCase()];
|
||||
let length = letters.length;
|
||||
const copy = new Set(blocks);
|
||||
|
||||
letters.forEach(letter => {
|
||||
for (let block of copy) {
|
||||
const index = block.indexOf(letter);
|
||||
|
||||
if (index !== -1) {
|
||||
length--;
|
||||
copy.delete(block);
|
||||
break;
|
||||
}
|
||||
}
|
||||
});
|
||||
return !length;
|
||||
}
|

```
