Understanding the Coding Pattern

In this type of coding-decoding question, we need to identify the rule or pattern applied to transform the given words into their coded forms. We are given two examples:

• "PRECIOUS" is coded as "UOICERPS"
• "FLAGRANT" is coded as "NARGALFT"

We need to find the code for "CHILDISH" using the same pattern.

Analyzing the Transformation for PRECIOUS

Let's look at the word "PRECIOUS" and its coded form "UOICERPS". Both words have 8 letters. Let's assign positions to the letters in the original word:

Now let's look at the coded word "UOICERPS":

Let's see which letter from the original word goes to which position in the coded word:

• The letter at Original Position 1 (P) is at Coded Position 7 (P).
• The letter at Original Position 2 (R) is at Coded Position 6 (R).
• The letter at Original Position 3 (E) is at Coded Position 5 (E).
• The letter at Original Position 4 (C) is at Coded Position 4 (C).
• The letter at Original Position 5 (I) is at Coded Position 3 (I).
• The letter at Original Position 6 (O) is at Coded Position 2 (O).
• The letter at Original Position 7 (U) is at Coded Position 1 (U).
• The letter at Original Position 8 (S) is at Coded Position 8 (S).

So, the pattern for the position mapping is:

This means the first 7 letters of the original word are reversed in position, while the 8th letter remains in its original position.

Verifying the Pattern with FLAGRANT

Let's apply this pattern to the second example, "FLAGRANT":

Original Word: F L A G R A N T

Original Positions: 1 2 3 4 5 6 7 8

Applying the pattern (1-7 reversed, 8 stays):

• Letter at Orig Pos 7 (N) goes to Coded Pos 1.
• Letter at Orig Pos 6 (A) goes to Coded Pos 2.
• Letter at Orig Pos 5 (R) goes to Coded Pos 3.
• Letter at Orig Pos 4 (G) goes to Coded Pos 4.
• Letter at Orig Pos 3 (A) goes to Coded Pos 5.
• Letter at Orig Pos 2 (L) goes to Coded Pos 6.
• Letter at Orig Pos 1 (F) goes to Coded Pos 7.
• Letter at Orig Pos 8 (T) goes to Coded Pos 8.

Coded Word: N A R G A L F T

This matches the given coded word "NARGALFT". The pattern is confirmed.

Applying the Pattern to CHILDISH

Now let's apply the same pattern to the word "CHILDISH":

Original Word: C H I L D I S H

Original Positions: 1 2 3 4 5 6 7 8

Applying the pattern (1-7 reversed, 8 stays):

• Letter at Orig Pos 7 (S) goes to Coded Pos 1.
• Letter at Orig Pos 6 (I) goes to Coded Pos 2.
• Letter at Orig Pos 5 (D) goes to Coded Pos 3.
• Letter at Orig Pos 4 (L) goes to Coded Pos 4.
• Letter at Orig Pos 3 (I) goes to Coded Pos 5.
• Letter at Orig Pos 2 (H) goes to Coded Pos 6.
• Letter at Orig Pos 1 (C) goes to Coded Pos 7.
• Letter at Orig Pos 8 (H) goes to Coded Pos 8.

Constructing the Coded Word for CHILDISH

Combining the letters in the coded positions, we get the coded word "SIDLIHCH".

Comparing with Options

Let's check the generated code "SIDLIHCH" against the given options:

1. HCSIDLIH
2. SIDLIHCH
3. SCHILDIH
4. HSIDLIHC

The coded word "SIDLIHCH" matches Option 2.

Conclusion

The code language follows a pattern where the first seven letters of the original word are reversed in their positions, and the eighth letter remains in the same position. Applying this rule to "CHILDISH" gives the coded word "SIDLIHCH".

Additional Information: Types of Coding

Coding-decoding questions can involve various types of patterns:

• Letter Shifting: Each letter is shifted a fixed number of positions forward or backward in the alphabet (e.g., A becomes C, B becomes D, etc.).
• Direct Letter Coding: Each letter in the original word is assigned a specific code letter, number, or symbol.
• Letter Rearrangement: The letters of the original word are simply reordered based on a rule (as seen in this problem).
• Mixed Coding: A combination of letter shifting and rearrangement, or other complex rules.
• Number/Symbol Coding: Words are coded using numbers or symbols based on letter positions, values, or other patterns.

Understanding these common types helps in quickly identifying the pattern in coding-decoding problems.
