I have a set with certain strings, it's a vector, I need to do character searches in this set.
Case:
V my set of strings contemplated by: ["ana", "paula", "cris", "voa", "karmanguia"];
P my search, I want to check in the set V the occurrence of P in these strings. I want you to return confirmation of the occurrence of such a character and where.
const V = ["ana", "paula", "cris", "voa", "karmanguia"];
const P = 'a';
const res = V.reduce((found, string, i) => {
const stringHasLetter = string.includes(P); // para saber se essa string tem a letra pretendida
if (!stringHasLetter) return found;
// para saber quais as posições da letra dentro da string
const letterPositions = string.split('').map(
(l, idx) => l == P && idx
).filter(nr => typeof nr == 'number').join(', ')
return found.concat({
vIndex: i,
letterPositions: letterPositions
});
}, []);
console.log(res);The idea is to search each string and return the results in each string as well.
