ADC converts analog signals into digital data by sampling the input signal at regular intervals.
ADC samples the input signal at regular intervals
It quantizes the sampled values into discrete digital values
The resolution of ADC determines the number of possible digital values
Common types of ADC include successive approximation ADC and delta-sigma ADC

To reverse an array of strings, iterate through the array and swap elements from start to end.
Iterate through the array using two pointers, one starting from the beginning and the other from the end.
Swap elements at the two pointers until they meet in the middle.
Repeat until all elements are swapped and the array is reversed.
