pH is a measure of acidity or alkalinity of a solution, ranging from 0 to 14.
pH stands for 'potential of Hydrogen'
It is a logarithmic scale, with 7 being neutral, below 7 acidic, and above 7 alkaline
Examples: Lemon juice has a pH of around 2, pure water is around 7, and baking soda is around 9
Acids have a pH below 7 due to the presence of excess hydrogen ions.
Acids release hydrogen ions (H+) in water, lowering the pH below 7.
The pH scale ranges from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 basic.
Examples of acidic substances include lemon juice (pH 2), vinegar (pH 3), and battery acid (pH 1).
A buffer is a temporary storage area that holds data before it is processed or transferred.
Types of buffers include input buffer, output buffer, circular buffer, and FIFO buffer.
Buffers help in managing data flow between different components in a system.
Examples of buffers include keyboard buffer, printer buffer, and network buffer.
Titration is a technique used to determine the concentration of a substance in a solution by reacting it with a known concentration of another substance.
Titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration until the reaction reaches its endpoint.
The endpoint is usually indicated by a color change or other observable change, such as a sudden pH shift.

Different types of titration include acid-base titration, redox titration, complexometric titration, and precipitation titration.
Acid-base titration involves the neutralization of an acid with a base or vice versa.
Redox titration involves a redox reaction between the analyte and titrant.
Complexometric titration involves the formation of a complex between the analyte and titrant.
Precipitation titration involves the form...

The task is to encode and decode 'SECRET_INFORMATION' for security purposes and determine if the transmission was successful.
Read the number of test cases 'T'
For each test case, encode the 'SECRET_INFORMATION' and then decode it
Compare the decoded string with the original 'SECRET_INFORMATION'
Print 'Transmission successful' if they match, else print 'Transmission failed'

An index is considered as an equilibrium index if the sum of elem...
Find the equilibrium index of an array where sum of elements on left equals sum on right.
Iterate through the array and calculate prefix sum and suffix sum at each index.
Compare prefix sum and suffix sum to find equilibrium index.
Return the left-most equilibrium index or -1 if none found.
