// // Exercise: // // You are given array @A containing positive numbers and @B containing // one or more indices from the array @A. // Write a script to left rotate @A so that the number at the first index // of @B becomes the first element in the array. Similary, left rotate @A // again so that the number at the second index of @B becomes the first // element in the array. // // We will be reading the arrays from STDIN -- @A is one the first // line, @B is on the second line. // // // Read two lines from STDIN, turn it into a string, strip off the // trailing newline (and any leading or trailing whitespace), // and then split in on spaces. Store the result into an arrays A and B. // let fs = require ("fs"); let lines = fs . readFileSync (0) . toString () . split ("\n"); let A = lines [0] . trim () . split (" "); let B = lines [1] . trim () . split (" "); // // Iterate over the array B, and print the slices of A. // for (let i = 0; i < B . length; i ++) { let index = +B [i]; console . log (A . slice ( index) . join (" ") + " " + A . slice (0, index) . join (" ")); }
