The following two questions only need to replace the getrandom () function in the code above.
2, JS implementation randomly selected (10,100] in 10 integers, stored in an array, and sorted.
1 function Getrandom (istart,iend) {2 var ichoice = istart-iend; 3 return Math.Abs (Math.floor (Math.random () *ichoice)) +istart; The floor () method can be rounded down by a number. 4 }3, JS implementation randomly selected [10,100] in 10 integers, stored in an array, and sorted.
1 function Getrandom (istart,iend) {2 var ichoice = istart-iend-1; 3 return Math.Abs (Math.ceil (Math.random () *ichoice)) +istart; 4 }The
JS implementation randomly selects the 10 integers in [10,100], deposits an array, and sorts. Also consider (10,100] and [10,100] two cases.
