Construct an equivalent grammar without left recursion:

$EE+T|T||$

$T{T}^{**}F|F||$

$F(E)|id||$

Rewrite the given grammar to remove left recursion:

$xx-Y|Y||$

$Y\frac{Z}{W}|W||$

$Wid$

Eliminate left recursion from the following grammar:

$AA+B|A**B|B$

$Bid|$ num $||$

Does the grammar below contain left recursion? If so$,$ remove it:

$RR+S|S||$

$Sid$

For the following grammar, construct a new grammar that eliminates all left recursion issues $($if any exist$).$

$PQ$

$QR|Q-R|\frac{Q}{R}$

$RS|S**R|S+R$

$Sid|(Q)||$
