skip some iteration in ruby for loop -

how can achieve in loop in ruby:

for(int = 1;i<=10;i++){         if (i == 7){             i=9;         }         #some code here     } 

i meant it's okay use "next" skip if want jump uncertain iteration via changing variable value itself. far know loop works enumerable type. want loop via index variable, way in c++

there few things can do:

incase want skip few iterations based on defined logic, can use:

next if condition 

if intention randomly iterate on whole range, can try this:

(1..10).to_a.shuffle.each { |i|     # code } 

incase want randomly iterate on chunk of given range, try this:

(1..10).to_a.shuffle.first(n).each { |i| # n number within 1 10   # code }
