(1) Write a C program using the arrays to eliminate the duplicate numbers. Generate 50 random numbers between 50 and 150 using rand function. Insert the random numbers to the array with a size 50. As each number is generated, print it only if it's not a duplicate of a number already generated. Provide for the "worst-case in which all 50 numbers are different. Hint: Calculate the frequency of each number as each number is generated using the arrays and print the numbers which occurred only one time such that, frequencyG]=1
