1. A continuación se muestran algunos ejemplos que comienzan con un nivel simple a avanzado (problema del vendedor ambulante y problema de la mochila 0/1)
2. Estos ejemplos se basan en Algoritmo de fuerza bruta

Mi nota:-

1. Hay varias desventajas de este algoritmo de fuerza bruta, pero antes de saltar directamente a la programación dinámica y otros enfoques
2. debe tener ideas sobre este enfoque y debe descubrir por qué necesitamos un patrón de programación dinámica (memorización recursiva)

Si observas de cerca el patrón de la fuerza bruta

const wrapper = (value) => {
    const helper = (combinedArray, depth) => {
       if (depth == 3) {
          // operation
           return ;
       }

       for (let coin of coins) {
           if (value - coin >=0) {
               combinedArray.push(coin);
               helper(combinedArray, label 1);
               combinedArray.pop();
           }
       }
    }

    helper([], 0);
    return result;
};

const res = wrapper(value);
console.log(res);

P1. Comience con 2 combinaciones de monedas

P5. Generación de conjuntos


// Problem 1: Generating All Subsets of a Set
// Problem Statement:
// Given a set of unique elements, generate all possible subsets (the power set).
