Check out my awesome coding creation from the Grasshopper Gallery!
Snippet Name: Subsequence
Description: Hi there, @Grasshopper_Ben. I made this code snippet today. This is my own code. Hope you get impressed. 
Your code so far:
let dictionaryWord = pickRandom(['lull', 'hub', 'boo', 'quack', 'balloon', 'hall']);
function findNextIndex(mappedIndices, lastMatchedIndex) {
for (var index of mappedIndices) {
if (index >= lastMatchedIndex) {
return index + 1;
}
}
return false;
};
const makeMap = (o) => {
var out = '';
for (var p in o) {
out += p + ': [' + o[p] + ']' + ', ';
console.log(out);
out = '';
}
return o;
};
let stringSequence = {
h: [0],
u: [1],
l: [2, 3, 7, 8],
a: [4, 6],
b: [5],
o: [9, 10]
};
console.log(dictionaryWord);
let stringSequenceObject = makeMap(stringSequence);
function isSubsequence(word, map) {
let minIndex = 0;
for (var letter of word) {
if (map[letter]) {
minIndex = findNextIndex(map[letter], minIndex);
if (minIndex = false) {
return false;
}
} else {
return false;
}
}
return true;
};
console.log(isSubsequence(dictionaryWord, stringSequenceObject));
@Grasshopper_Ben, you might get impressed it!
Thank you!
