I've an array of strings or numbers of size M(M>n). I want to check if any n consecutive elements are same where n can vary between 1-M.
For instance, let assume I've below array, and I want to check there are four consecutive '5's or two consecutive '3's are present or not:
How can I achieve this?
P.S. I'm also using Linq.JS to perform linq functions on array.
You might do as follows
var arr = [1,2,3,4,5,5,5,5,2,6,3,3,1], result = arr.reduce((p,c,i,a) => c !== a[i+1] ? (p[p.length-1] = c, p.concat([[0,1]])) : (p[p.length-1] = c, p[p.length-1]++, p),[[true,1]]) .slice(0,-1); console.log(result);
