There are n bulbs numbered from 1 to n, arranged in a row. the first bulb is plugged into the power socket and each successive bulb is connected to the previous one. (second bulb to first, third to second) initially, all the bulbs are turned off. a moment k (for k from 0 to n-1), the a[k]-th bulb is turned on. a bulbs shines if it is one and all the previous bulbs are turned on too. write a function in java that given an array a of n different integers from 1 to n, returns the number of moments for which every turned on bulb shines.

Write a new lc-3 trap subroutine (i. e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i. e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e. g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e. g. b0000 0000 0000 0111 =
