Decode these using the reverse alphabet code. Example: STRAIN=PMAXLD, TRAIN=MAXLD.

This is a substitution cipher where each letter in the original word maps to a specific letter in the coded word. Your task is to find the code for a rearranged or partial version of the original word.

Here are the decoded words:

1. If NOTE = DBYW then TONE = N $\to$ D O $\to$ B T $\to$ Y E $\to$ W TONE $\to$ $\boxed{YBDW}$

2. If WHEAT = QPCTH then HEAT = W $\to$ Q H $\to$ P E $\to$ C A $\to$ T T $\to$ H HEAT $\to$ $\boxed{PCTH}$

3. If WHOLE = XTVYZ then HOLE = W $\to$ X H $\to$ T O $\to$ V L $\to$ Y E $\to$ Z HOLE $\to$ $\boxed{TVYZ}$

4. If YAM = UVX then MAY = Y $\to$ U A $\to$ V M $\to$ X MAY $\to$ $\boxed{XVU}$

5. If TOOLS = LKJVX then STOOL = T $\to$ L O $\to$ K O $\to$ J L $\to$ V S $\to$ X STOOL $\to$ $\boxed{XLKJV}$

6. If LOW = YWZ then OWL = L $\to$ Y O $\to$ W W $\to$ Z OWL $\to$ $\boxed{WZY}$

7. If BATS = LMYR then STAB = B $\to$ L A $\to$ M T $\to$ Y S $\to$ R STAB $\to$ $\boxed{RYML}$

8. If TOPS = VDEX then POTS = T $\to$ V O $\to$ D P $\to$ E S $\to$ X POTS $\to$ $\boxed{EDVX}$

9. If HELPER = LMDBXY then HELP = H $\to$ L E $\to$ M L $\to$ D P $\to$ B E $\to$ X R $\to$ Y HELP $\to$ $\boxed{LMDB}$

10. If MATES = DXVIP then STEAM = M $\to$ D A $\to$ X T $\to$ V E $\to$ I S $\to$ P STEAM $\to$ $\boxed{PVIDX}$
