Golang Channel Deadlock

The number of channels is limited and whenever we try to receive or send value from and to the channel out of number, a deadlock occurs.

1. Receiving channels more than expected

    go func(ch <-chan int) {        i := <-ch        j := <-ch        fmt.Println("Value of Channel i,j =", i, j)        wg.Done()    }(ch)Error:- fatal error: all goroutines are asleep – deadlock!

Here, there is only a single channel from where data is sent, and two receiving channels and thus Deadlock occurs.
